Roman Houses of Celio: Underground Rome Guide

The Roman Houses of the Caelian Hill are an archaeological complex beneath the Basilica of Saints John and Paul, preserving rooms that reveal centuries of change in ancient Rome.

Rome’s history can feel impossibly vast. Here it becomes intimate: surviving rooms and traces of wall decoration bring you closer to the spaces where people lived, worked and worshipped.

What makes this place special?

The complex includes rooms used and adapted across different periods, from earlier Roman structures to later residential and religious uses. Rome’s tourism office identifies the entrance on Clivo di Scauro and describes the site’s frescoed underground rooms.

How to plan your visit

Check current ticketing, opening days and the visitor route before leaving. Allow about an hour or more, and ask the site directly about steps and accessibility. The basilica is a place of worship, so check its separate access arrangements and dress respectfully.

Before you go, check visitor information from the site or Rome’s tourism office for changes to opening hours, admission and access.

Is it worth adding to your Rome itinerary?

If you want a trip that combines famous sights with a sense of discovery, this is an engaging addition. Consider how much time you have, how you will get there and whether the experience suits your interests and mobility needs. A well-planned itinerary leaves space to enjoy Rome rather than rush between stops.
