No city stacks up landmarks quite like Rome. Two thousand years of history stand shoulder to shoulder in a walkable centre — the Colosseum and Roman Forum, the perfect Pantheon, Bernini's fountains and the Vatican's peerless art. Here are the 20 attractions worth building your trip around, with prices, opening hours and tips to skip the queues.

Rome attractions in detail
1.Colosseum
The Colosseum is the single sight that defines Rome, an elliptical amphitheatre completed in AD 80 under the Flavian emperors and capable of seating some 50,000 people for gladiatorial combat, wild-beast hunts and mock naval battles. Two thousand years of earthquakes and stone-robbing have stripped its marble skin, yet the tiered arches and the exposed hypogeum — the warren of tunnels and lifts beneath the arena where gladiators and animals waited — still stop you in your tracks. The standard ticket is a 24-hour combo that also covers the Roman Forum and Palatine Hill, so plan those together. Entry is timed and sells out days ahead in peak season, so book online and arrive right at opening or in the last afternoon slot for thinner crowds and softer light. Paying a few euros more for arena-floor or underground access puts you where the action happened. Allow 1.5 hours, wear sturdy shoes for the uneven stone, and bring water in summer — there is little shade.
Hours
Daily 09:00 until one hour before sunset (last entry ~1h before close)
Price
From €18 combo (Colosseum + Forum + Palatine, valid 24h); arena floor +€6
Getting there
Metro line B to Colosseo (the exit faces the monument); trams 3 and 8, bus 51/75/85/87
Insider tip: Buy the timed 'Colosseo–Foro Romano–Palatino' combo online and enter at 08:30 to beat the tour groups.
2.Roman Forum
For over a thousand years the Roman Forum was the beating heart of the ancient world — the marketplace, law court, senate and religious centre where Rome governed an empire. Today it is a romantic field of ruins between the Capitoline and Palatine hills: the towering columns of the Temple of Saturn and Temple of Castor and Pollux, the Arch of Septimius Severus and Arch of Titus, the circular Temple of Vesta where the sacred flame burned, and the Curia where senators debated. The paving of the Via Sacra still runs through the middle, worn smooth by triumphal processions. It is included in the Colosseum combo ticket, so most visitors do all three sites in one long morning. There is almost no shade and the ground is rough underfoot, so wear good shoes, carry water and consider a guide or audio guide, because without context the stones can read as a jumble. Climb onto the Palatine afterwards for the classic elevated view back across the whole Forum.
Hours
Daily 09:00 until one hour before sunset
Price
Covered by the €18 Colosseum combo (24h)
Getting there
Metro line B to Colosseo; entrances on Via dei Fori Imperiali and Via di San Gregorio
Insider tip: Enter from the quieter Via di San Gregorio gate and walk uphill onto the Palatine for the best overview.
3.Palatine Hill
The Palatine is the most central of Rome's seven hills and, according to legend, where Romulus founded the city in 753 BC after the she-wolf raised him and Remus in a cave on its slopes. It later became the most exclusive address in the empire, where Augustus, Tiberius and Domitian built sprawling imperial palaces — the very word 'palace' derives from Palatino. Wandering the pine-shaded ruins you can trace the Domus Augustana, the stadium-shaped garden and the House of Livia with its delicate frescoes. The green Farnese Gardens, laid out in the sixteenth century over the palace of Tiberius, offer terraces with superb views down over the Roman Forum on one side and the Circus Maximus on the other. It is the quietest and leafiest section of the combined archaeological area, so it makes a restful finale after the crowds of the Colosseum and Forum. Allow an hour, bring water and enjoy the panoramas that emperors once claimed for themselves.
Hours
Daily 09:00 until one hour before sunset
Price
Covered by the €18 Colosseum combo (24h)
Getting there
Metro line B to Colosseo; enter via the Forum or the Via di San Gregorio gate
Insider tip: It is the calmest, greenest part of the combo — save it for last and enjoy the Farnese Gardens views.
4.Pantheon
The Pantheon is the miracle of Roman engineering — a temple rebuilt by Emperor Hadrian around AD 125 and preserved almost intact because it was consecrated as a church in the seventh century. Its coffered concrete dome, 43 metres across, remains the largest unreinforced concrete dome ever built, and at its centre the oculus, a nine-metre circular opening, floods the interior with a moving shaft of daylight and, occasionally, rain that drains through holes in the sloped marble floor. Step through the massive bronze doors and the geometry is overwhelming: the height to the oculus exactly equals the diameter, so a perfect sphere would fit inside. It is also a working church and the tomb of the artist Raphael and two Italian kings. A small timed-entry fee now applies, and lines move quickly. Come at opening for near-empty calm, or time a visit for a rain shower to see the famous column of falling water. It sits on a lively piazza with cafés — the perfect spot for a post-visit espresso.
Hours
Mon–Sat 09:00–19:00, Sun 09:00–18:00 (last entry ~30 min before)
Price
€5 (free for under-18s; timed tickets recommended in peak season)
Getting there
Buses 30/40/62/64/81 to Largo di Torre Argentina, then a 5-minute walk; nearest Metro is Barberini (line A)
Insider tip: Go at opening or on a rainy day to watch water fall through the open oculus onto the marble floor.
5.Trevi Fountain
The Fontana di Trevi is Baroque Rome at its most exuberant — a 26-metre wall of travertine and Carrara marble completed by Nicola Salvi and Giuseppe Pannini in 1762, where the god Oceanus rides a shell chariot pulled by sea horses and tritons over a cascade fed by an ancient Roman aqueduct, the Aqua Virgo. The custom is to stand with your back to the water and throw a coin over your left shoulder to guarantee a return to Rome; the roughly €3,000 collected each day is donated to charity. It is one of the city's most crowded spots, wedged into a small piazza, so the experience swings entirely on timing: at midday you will fight for a view, but before eight in the morning or late at night, floodlit and near-silent, it is genuinely magical. Climbing into or wading in the fountain is illegal and fined. It is free, always open and only a short walk from the Pantheon and Spanish Steps, so weave it into an evening passeggiata with a gelato in hand.
Hours
Always open (best lit and quietest late at night)
Price
Free
Getting there
Metro line A to Barberini or Spagna, then a 5–10 minute walk through the lanes
Insider tip: Come before 08:00 or after 23:00 to see it near-empty and beautifully lit — daytime is a scrum.
6.Vatican Museums & Sistine Chapel
The Vatican Museums hold one of the richest art collections on earth, amassed by popes over five centuries and displayed along seven kilometres of galleries. The route sweeps past Egyptian antiquities, the Laocoön and Apollo Belvedere in the octagonal courtyard, the tapestry and map galleries, and the Raphael Rooms with the philosophers of the School of Athens, before delivering you to the finale that everyone comes for: the Sistine Chapel, where Michelangelo painted the ceiling's Creation of Adam between 1508 and 1512 and, decades later, the vast Last Judgment behind the altar. It is also where cardinals gather in conclave to elect a pope. Crowds are intense, so a timed online ticket is essential; the earliest morning slot or a Friday-evening opening gives the calmest experience, and the free last-Sunday queues are enormous. Dress modestly — knees and shoulders covered — as it is a sacred site, and no photos are allowed in the chapel. Allow at least three hours, and combine it with St Peter's next door.
Hours
Mon–Sat 08:00–19:00 (last entry 17:00); some Friday evenings; closed most Sundays except the last of the month (free)
Price
€20 online (+€5 booking fee); guided tours from ~€45
Getting there
Metro line A to Ottaviano or Cipro, then a 10-minute walk to the entrance on Viale Vaticano
Insider tip: Book the earliest timed slot or a Friday-evening opening; the Sistine Chapel is quietest right at opening.
7.St Peter's Basilica
St Peter's Basilica is the grandest church in Christendom, built over the tomb of the apostle Peter and completed in 1626 after 120 years of work by Bramante, Michelangelo, Maderno and Bernini. The scale defies belief: markers in the marble floor show how the world's other great cathedrals would fall short of its length. Inside are treasures at every turn — Michelangelo's aching Pietà, sculpted when he was just 24 and now behind glass, Bernini's twisting bronze baldachin soaring over the papal altar, and his gilded Chair of St Peter glowing in the apse. Entry to the basilica is free, but security lines can be long, so arrive early. The undisputed highlight for many is the climb to the top of Michelangelo's dome, 551 steps (or a lift for the first stretch) up between the double shells to a walkway with the finest panorama in Rome, straight down over St Peter's Square. Dress modestly, covering shoulders and knees, and pair the visit with the Vatican Museums.
Hours
Daily 07:00–19:10 (Oct–Mar until 18:30); dome 07:30–18:00
Price
Basilica free; dome climb €8 stairs / €10 lift + stairs
Getting there
Metro line A to Ottaviano, then a 10-minute walk; bus 40/64 to Piazza Pia
Insider tip: Arrive by 07:30 to walk straight in; climbing the dome (€10) rewards you with the best view in Rome.
8.Spanish Steps
The Scalinata di Trinità dei Monti — the Spanish Steps — is one of Rome's great set pieces, a monumental sweep of 135 travertine steps built in the 1720s to link the Piazza di Spagna below with the twin-towered Trinità dei Monti church at the top. The name comes from the nearby Spanish Embassy to the Holy See. In spring the terraces blaze with pink azaleas, and the elegant curves have drawn poets and painters for centuries — John Keats died in the pink house to the right of the steps, now a museum to him and Shelley. At the foot sits Bernini's Barcaccia, a half-sunken stone boat fountain fed by the same ancient aqueduct as the Trevi. Note that since 2019 sitting on the steps is forbidden and carries a fine, so treat them as a stage to walk and photograph rather than lounge. The surrounding streets — Via dei Condotti and its neighbours — form Rome's luxury shopping quarter. Climb to the church at the top for a fine view back over the rooftops toward St Peter's.
Hours
Always open
Price
Free (note: sitting on the steps is prohibited)
Getting there
Metro line A directly to Spagna (the station opens onto the piazza)
Insider tip: Sitting on the steps is banned and fined — admire from the Barcaccia fountain or climb to the church at the top.
10.Borghese Gallery
The Galleria Borghese is Rome's most rewarding art experience — a seventeenth-century pleasure villa built by the art-collecting Cardinal Scipione Borghese and set in the city's great park. Its rooms hold an astonishing concentration of genius, above all the young Gian Lorenzo Bernini's marble sculptures, which seem to defy the stone: Apollo and Daphne caught at the instant she turns into a laurel tree, Pluto's fingers pressing into the yielding flesh of Proserpina, and a coiled David mid-throw. Alongside them hang six Caravaggios, Raphael's Deposition, Titian's Sacred and Profane Love and Canova's reclining marble of Pauline Bonaparte. To protect the collection, visits are strictly timed to two-hour slots with a capped number of guests, and tickets routinely sell out weeks in advance, so reserving online before your trip is essential. The intimacy is part of the pleasure — you are never in a crush. Afterwards, stroll the surrounding Villa Borghese gardens, hire a rowing boat on the little lake, or walk to the Pincio terrace for a sunset view over the city.
Hours
Tue–Sun 09:00–19:00 (timed two-hour entry slots; closed Mon)
Price
€15 + €2 booking (compulsory advance reservation)
Getting there
Metro line A to Spagna and walk up through the park, or bus 53/63/83/92 to Via Pinciana
Insider tip: Timed tickets are compulsory and sell out weeks ahead — book online before you fly, then walk the park.
11.Castel Sant'Angelo
Castel Sant'Angelo has worn more identities than almost any building in Rome. It began around AD 139 as a towering cylindrical mausoleum for Emperor Hadrian and his successors, was fortified into a papal stronghold in the Middle Ages, served as a refuge for popes fleeing danger — reached from the Vatican by the Passetto di Borgo, a raised escape corridor along the walls — and later became a grim prison and barracks. Today a spiralling ramp and staircases climb through military halls, papal apartments frescoed in Renaissance splendour, dank cells and a small museum of arms, all the way to the rooftop terrace crowned by a bronze angel. That terrace, immortalised as the finale of Puccini's opera Tosca, delivers one of the finest views in the city: the Tiber curling below, the statue-lined Ponte Sant'Angelo in the foreground and the dome of St Peter's beyond. There is a café at the top for a drink with the panorama. It pairs perfectly with a Vatican visit just across the river.
Hours
Tue–Sun 09:00–19:30 (last entry 18:30; closed Mon)
Price
€16 (may rise for exhibitions)
Getting there
Metro line A to Lepanto, 10-minute walk; bus 40/62 to Piazza Pia; cross the statue-lined Ponte Sant'Angelo
Insider tip: Climb to the rooftop terrace café at sunset for a postcard view straight down the river to St Peter's.
12.Trastevere
Trastevere — literally 'across the Tiber' — is the Rome of everyone's imagination: a warren of narrow cobbled lanes and ochre houses draped in ivy, washing strung overhead, mopeds threading between trattoria tables and church bells echoing off the stone. Long a working-class district slightly apart from the city, it has kept a village feel even as it became a nightlife magnet. Its heart is Piazza di Santa Maria in Trastevere, dominated by one of Rome's oldest churches, its façade and interior shimmering with twelfth-century gold mosaics; nearby, Santa Cecilia and the Villa Farnesina with its Raphael frescoes reward a detour. By day the quarter is quiet and photogenic, full of artisan workshops, tiny galleries and gelaterias; by night it transforms into the liveliest dining and drinking scene in the city, its squares filling with locals and students over cacio e pepe and carafes of house wine. It is free to explore and endlessly atmospheric — come with no fixed plan, get pleasantly lost, and let dinner drift into a late-evening stroll.
Hours
Always open; churches ~08:00–12:00 & 16:00–19:00
Price
Free to explore
Getting there
Tram 8 from Piazza Venezia to Trastevere; bus H; or a 15-minute walk across the river from Campo de' Fiori
Insider tip: Wander the lanes west of Viale di Trastevere by day, then return after dark for the buzzing dinner scene.
13.Campo de' Fiori
Campo de' Fiori is one of the few central Roman squares without a church, and it has a darker history to match: in its centre stands a brooding statue of the philosopher Giordano Bruno, burned at the stake here for heresy in 1600 and now a symbol of free thought. By day the 'field of flowers' hosts a long-running open-air market of fruit, vegetables, flowers, spices and souvenirs — increasingly geared to tourists but still colourful and good for photos and picnic supplies. As the stalls pack away, the square shifts character completely, its ring of bars and restaurants filling with a young, boisterous crowd for aperitivo and beyond, making it one of the city's most reliable spots for an early-evening drink. The lanes fanning out from it lead to the Palazzo Farnese, Via Giulia and the Jewish Ghetto, all worth a wander. Prices on the square itself are aimed squarely at visitors, so eat in the side streets, but do come at least once for the buzz — few places capture Rome's easy sociability better at dusk.
Hours
Market Mon–Sat ~07:00–14:00; bars until late
Price
Free
Getting there
Buses 40/64/916 to Corso Vittorio Emanuele II, then a 3-minute walk
Insider tip: The morning market (Mon–Sat) is touristy but fun; the real show is the packed bars at aperitivo hour.
14.Capitoline Museums
Founded in 1471, the Musei Capitolini are the oldest public museums in the world, spread across two palaces on the Piazza del Campidoglio, the elegant hilltop square Michelangelo designed in the sixteenth century. The collection is a roll-call of ancient icons: the bronze Capitoline She-Wolf suckling Romulus and Remus, the poignant Dying Gaul, the gilded equestrian statue of Marcus Aurelius (the original, with a copy outside in the square), and the giant marble head, hand and foot of a colossal Constantine that once towered over the Forum. Upstairs, a picture gallery adds Caravaggio, Titian and Rubens. A tunnel links the two palaces via the Tabularium, ancient Rome's record office, whose arched gallery frames a breathtaking, less-crowded panorama over the Roman Forum. It is a superb, manageable museum that many visitors overlook in favour of the Vatican, which means shorter queues and more room to breathe. Allow two hours, and step out afterwards onto the terrace behind the square for another fine view across the Forum toward the Palatine.
Hours
Daily 09:30–19:30 (last entry 18:30)
Price
€16 (higher with temporary exhibitions)
Getting there
Buses to Piazza Venezia, then climb the Cordonata ramp; nearest Metro is Colosseo (line B)
Insider tip: The Tabularium gallery frames a spectacular window over the Roman Forum — worth the ticket alone.
15.Baths of Caracalla
The Terme di Caracalla are among the most impressive and least crowded ancient ruins in Rome — a vast public bathing complex opened around AD 216 that could accommodate some 1,600 people at once. Far more than a place to wash, these thermae were a leisure city under one roof, with a cold-water frigidarium, a warm tepidarium, a domed hot caldarium, an Olympic-sized swimming pool, gymnasiums, libraries and gardens, all heated by an underground network of furnaces and served by their own aqueduct branch. Today the towering brick walls still soar 30 metres high, and patches of the original mosaic floors survive, giving a real sense of the imperial scale. Because they sit slightly off the main tourist trail near the Aventine Hill, you can often explore in relative peace. In summer the ruins become a magical open-air stage for the Rome Opera's productions, floodlit against the night sky. Good multimedia reconstructions and occasional virtual-reality headsets help you picture the marble-clad splendour. Allow an hour, and combine it with the nearby Aventine and its famous keyhole view of St Peter's dome.
Hours
Tue–Sun 09:00 until ~sunset; Mon 09:00–14:00
Price
€8 (higher during summer opera season)
Getting there
Metro line B to Circo Massimo, then a 10-minute walk; bus 118/160
Insider tip: Go on a summer evening when it hosts open-air opera among the floodlit ruins — an unforgettable night.
16.Appian Way
The Via Appia Antica, begun in 312 BC, was ancient Rome's most important road — the 'regina viarum' that ran all the way to Brindisi on the Adriatic and along which armies marched, trade flowed and, infamously, the rebel slaves of Spartacus were crucified. Roman law forbade burials inside the city, so the road out of town became lined with grand tombs, mausoleums and, later, the underground Christian catacombs. Today a stretch of it is protected as a regional park, and walking or cycling the original basalt paving beneath towering umbrella pines, past crumbling tombs and green fields, is one of the most atmospheric and least touristy things to do in Rome. Highlights include the Catacombs of San Callisto and San Sebastiano, the round tomb of Cecilia Metella and the ruins of the Villa dei Quintili. The road is at its best on Sundays, when much of it closes to cars. Hire a bike at the park entrance, pack a picnic and give it half a day; it feels a world away from the crowded centre.
Hours
Road always open; visitor centre & sites ~09:00–17:00
Price
Road free; catacombs ~€10; bike hire ~€15/day
Getting there
Bus 118 from Circo Massimo to the park; or Metro line A to Colli Albani + bus 660
Insider tip: Rent a bike near the park entrance on a Sunday, when the old road is closed to traffic and blissfully quiet.
17.Piazza del Popolo
Piazza del Popolo is the monumental oval that for centuries greeted travellers arriving in Rome from the north through the Porta del Popolo in the old city walls. Redesigned in neoclassical style in the early nineteenth century, it is anchored by a 3,000-year-old Egyptian obelisk brought to Rome by Augustus, framed by symmetrical fountains and the near-identical domes of the 'twin' churches of Santa Maria in Montesanto and Santa Maria dei Miracoli at the mouth of the trident of streets running south. The unmissable art hides in the church of Santa Maria del Popolo on the north side, which holds two dramatic Caravaggios — the Conversion of St Paul and the Crucifixion of St Peter — plus a Raphael-designed chapel, all free to view. The square is a car-free social space, good for people-watching, and above it rises the Pincio hill: climb the zigzag ramp to its terrace for one of Rome's most beloved sunset views, looking back over the piazza's obelisk and out across the domes of the city toward St Peter's.
Hours
Always open; churches ~07:30–12:30 & 16:00–19:00
Price
Free
Getting there
Metro line A directly to Flaminio, at the northern edge of the square
Insider tip: Climb the ramp to the Pincio terrace above for a classic sunset panorama over the whole square and city.
18.Santa Maria Maggiore
Basilica di Santa Maria Maggiore is the largest of Rome's churches dedicated to the Virgin Mary and one of the four great papal basilicas, founded in the fifth century after, legend says, a miraculous August snowfall marked out its footprint on the Esquiline Hill — an event still commemorated each year with a shower of white petals. It has been continuously in use for over 1,500 years, which makes its layers of art extraordinary: the fifth-century mosaics running high along the nave depicting Old Testament scenes are among the oldest in the city, while the flat coffered ceiling is said to be gilded with the very first gold brought back from the Americas, a gift from the Spanish crown. Below lie the tomb of the great Baroque sculptor Bernini and a relic said to be from the manger of the Nativity. It became the burial place of Pope Francis in 2025. Entry to the basilica is free; a small fee gives access to the museum, the ancient underground level and the loggia mosaics. It sits an easy walk from Termini station, so it is convenient to slot in on arrival or departure.
Hours
Daily 07:00–18:45
Price
Free (museum & loggia extra ~€5)
Getting there
Metro line A or B to Termini, then a 5-minute walk; many buses to Piazza dell'Esquilino
Insider tip: The fifth-century mosaics high in the nave are the treasure — bring a zoom or use the coin-operated lights.
19.Catacombs of San Callisto
The Catacombs of San Callisto are the largest and most important of Rome's early-Christian burial complexes, a labyrinth of galleries carved on multiple levels into the soft volcanic tufa beneath the Appian Way. Roman law banned burial within the city, and because land was expensive and Christians wished to be interred together near the martyrs, they dug downward, eventually creating some twenty kilometres of tunnels here alone, holding an estimated half a million tombs. San Callisto became the official cemetery of the early Church and the resting place of numerous third-century popes in the so-called Crypt of the Popes, as well as of St Cecilia. Visits are by guided tour only, led along a lit section of the passages while a guide explains the burial niches, the early Christian symbols scratched into the stone — the fish, the anchor, the Good Shepherd — and the faith of a persecuted community. It is genuinely atmospheric and a little sombre, a striking counterpoint to the imperial monuments above ground. It is cool underground year-round, so bring a layer, and check the seasonal closing days before setting out.
Hours
Thu–Tue 09:00–12:00 & 14:00–17:00 (closed Wed & parts of winter); guided tours only
Price
€10 (under-16s €7)
Getting there
Bus 118 from Circo Massimo to Catacombe di San Callisto; or Metro line A to Colli Albani + bus 660
Insider tip: Guided visits only and it is cool underground — bring a light layer even in summer and check closing days.
