Rome

Stand in the Pantheon at noon and watch the disc of light from the oculus crawl across marble that has not moved since Hadrian's masons dedicated it around AD 126. Rome rewards the patient. The city stacks its eras vertically and sideways: a 19-BC aqueduct still feeds the Trevi Fountain, a Renaissance ceiling hangs above a chapel finished in 1480, and somewhere below your feet a sewer dug by kings still drains. You will not see it in three days. Nobody has. What you can do is choose well, walk slowly, and let the layers argue with each other while you listen.

From a riverside settlement to an empire

Tradition fixes the founding on 21 April 753 BC, a date the scholar Marcus Terentius Varro calculated in the first century BC and which Romans still celebrate as the Natale di Roma. The story of Romulus, Remus and the she-wolf is myth; the archaeology of huts on the Palatine is not. For roughly two and a half centuries Rome was ruled by kings. Around 509 BC they were thrown out and the Republic began, the long, quarrelsome experiment that eventually governed the Mediterranean.

The Flavian century in stone

The monument tourists call the Colosseum was the Flavian Amphitheatre. Vespasian began it around AD 72 on the drained lake of Nero's confiscated pleasure-palace, a deliberately populist gesture, handing back to the public a site a hated emperor had seized. His son Titus completed it in AD 80 and opened it with games that ran more than a hundred days. Titus had inherited a grim moment, the eruption of Vesuvius in AD 79, a fire, a plague, and the spectacle was partly an apology to gods and citizens alike.

The Pantheon belongs to the next generation. An earlier temple by Agrippa burned; Hadrian rebuilt it entirely, with the rotunda dedicated around AD 126. Its dome remains the largest unreinforced concrete dome on Earth, lightened by an oculus and by aggregate that grows steadily lighter toward the top, travertine at the base, pumice near the crown.

Popes, painters and a new capital

Centuries later the popes rebuilt Rome as a stage for faith. Sixtus IV raised the Sistine Chapel between 1477 and 1480; Michelangelo frescoed its ceiling between 1508 and 1512, finishing in time for Mass on 1 November 1512. In the next century Bernini drew the great elliptical colonnade of St Peter's Square, commissioned by Alexander VII in 1656 and finished in 1667, its 284 columns curving outward like, in Bernini's words, the arms of the Church. The Trevi Fountain, designed by Nicola Salvi and completed by Giuseppe Pannini in 1762, still pours from the restored Aqua Virgo, the aqueduct delivered in 19 BC.

You can group most of Rome into three clusters and walk between them, which is how the city is best understood anyway, on foot, getting briefly lost.

The ancient core. The Colosseum, Roman Forum and Palatine Hill sit on one ticket as a single archaeological park, which drew nearly 15 million visitors in 2024, more than any other site in Italy. Buy a timed slot in advance; turning up cold in summer means a long, sunstruck queue. The Forum is where the Republic actually happened, a field of broken columns that needs a little imagination or a good guide to come back to life.

The Baroque centre. This is the Rome of fountains and piazzas, best done as a loose evening walk:

• The Pantheon, almost intact after nearly nineteen centuries. Since 1 July 2023 there is a modest entry fee (capped at 5 euros); Raphael is buried inside.
• The Trevi Fountain, where roughly 3,000 euros in coins are fished out daily and given to the Catholic charity Caritas.
• Piazza Navona and the Spanish Steps, a few minutes apart.

The Vatican. St Peter's Basilica and Square cost nothing to enter, though the security line is long. The Vatican Museums, ending at the Sistine Chapel, drew 6.8 million people in 2024 and reward an early or late booked slot far more than a midday walk-up.

If you only have a morning, choose one cluster and go deep rather than sprinting between all three.

Aim for the shoulder seasons, roughly April to June and September to October, when temperatures sit around 15 to 25 degrees and the Colosseum queue is bearable. July and August are the honest problem: heat regularly hits the mid-30s and can spike past 38, the sun is merciless, and shade is scarce among the ruins. There is one quirk worth knowing. Around Ferragosto, 15 August, many Romans leave and a lot of small shops and trattorie shut for a week or two, so the streets feel calmer even as the big sites stay open and prices stay high. Late August eases as locals drift back. Winter is quiet, cheap and often mild, with the occasional gray rainy stretch.

Rome's centre is compact and walkable; you will use your feet more than any train. The metro has three lines, A, B and the newer C, with A and B crossing at Termini, the main hub, but the network is thin and skips much of the historic centre, so buses and trams fill the gaps. A standard BIT ticket costs 1.50 euros and is valid 100 minutes across metro, bus and tram, with unlimited surface transfers; 24, 48 and 72-hour passes exist for heavier days, and you can now buy and validate tickets by phone. Validate before you board or risk a fine. Carry some cash for small bars and markets, though cards are widely accepted. Tipping is light, rounding up or leaving a euro or two is plenty; a coperto (cover charge) is normal on the bill. Cover shoulders and knees to enter St Peter's and other churches, dress codes are enforced. Watch your bag on crowded buses and around Termini.
