The Caelian Hill: Rome's green hill behind the Colosseum

The Caelian is the hill almost every visitor sees from the Colosseum without climbing it. Ten minutes' walk away, its streets lined with walls, pines and medieval bell towers have a completely different feel: few tourists, a large park, churches steeped in history and some of the most interesting underground sites in Rome. This guide suggests a half-day walk, with the hours and prices of the paid sites checked in October 2026.

The Caelian in brief

The Caelian is one of the seven hills of Rome, south-east of the Colosseum, between the Palatine, the Esquiline and the Basilica of St John Lateran. In antiquity it was home to the houses of notables; in the Middle Ages, convents and churches took the place of the houses. What remains is a quiet, very green district where you can stroll without queuing.

Come in the morning or late afternoon. Churches have variable hours and often close at midday: check them before setting out.

A half-day walk

Stop 1: San Clemente

Five minutes' walk from the Colosseum, the Basilica of San Clemente is a good place to start: a free upper church, then three levels of excavations (€10, to be booked) down to a temple of Mithras. Photos are forbidden.

Stop 2: the Clivus Scauri and the Roman houses

The bell tower of Santi Giovanni e Paolo on the Caelian Hill

Climbing south-east, you reach Piazza dei Santi Giovanni e Paolo. Its medieval bell tower is built on the remains of a Roman temple. Beneath the basilica, the Case Romane del Celio (€8, €6 reduced) keep some twenty frescoed rooms from the 1st to the 4th century. Allow under an hour. Check the opening days before you come.

Stop 3: Villa Celimontana

The lawns and pines of Villa Celimontana

Next, enter the free park of Villa Celimontana: lawns, tall trees, an Egyptian obelisk, benches. It is the ideal place for a picnic. In summer, free concerts are held there in the evening.

Stop 4: the churches of the Caelian

Several churches on the hill are worth a look if they are open: Santo Stefano Rotondo, a very old circular church; Santa Maria in Domnica and the little Navicella fountain in front of it; and Santi Quattro Coronati, a fortified medieval complex with a cloister. Hours are short and change: the safest thing is to check on site or with the tourist office.

Stop 5: St John Lateran

The walk ends, to the north-east, in front of the Basilica of St John Lateran, the cathedral of Rome, with its baptistery and cloister. It is about twenty minutes' walk from San Clemente.

The Caelian in three formats

Two hours: San Clemente and Villa Celimontana.
A half-day: add the Case Romane del Celio and the churches.

Getting to the Caelian and eating nearby

Colosseo metro station (line B) is the closest, 10 minutes' walk away; Circo Massimo station (line B) serves the south side. For the Colosseum, allow five to ten minutes' walk from San Clemente. For food, head down to Monti (see our guide to Monti) or towards the Colosseum, avoiding restaurants with touts; there are few places to eat on the hill itself.
