Catacomb visits are free but must be booked in advance.

Rome's seven catacombs open to the public will offer free guided tours on Saturday 18 March as part of the spring 2023 edition of Day of the Catacombs.

Organised by the Pontifical Commission for Sacred Archaeology, the sixth Giornata delle Catacombe has as its theme "Paths of Peace".

The catacombs included in the initiative are those dedicated to S. Callisto, S. Sebastiano, Domitilla, Priscilla, S. Agnese, SS. Marcellino and Pietro, and S. Pancrazio.

In 2023 there are two special appointments scheduled to visit these fascinating underground burial chambers: one in spring devoted to catacombs that are open to the public and one in autumn for catacombs that are rarely opened to visitors.

• Rome opens Catacombs of Commodilla

Catacombs were developed between the end of the second and start of the third century AD for the burial and funeral commemoration of Christians.

Outside of Rome there are Christian catacombs in several Italian regions including Lazio, Tuscany, Umbria, Abruzzo, Campania, Puglia, Sardinia and Sicily.
