On Via Nomentana, outside central Rome, the Basilica of St. Agnes stands above the cemetery and catacombs associated with the saint. Built in 324 at the request of Constance, daughter of Emperor Constantine, it is an unusually intact early Christian basilica. Inside, look up at the ceiling, study the Latin inscriptions and artwork, and notice the mosaic. The underground areas and historical museum add another layer to a visit, but construction work has affected access, so check what is open before you go.
A basilica built above a cemetery
The Basilica of St. Agnes Outside the Walls was built in 324 at the request of Constance, daughter of Emperor Constantine. It stands above the remains of a cemetery and catacombs connected with St. Agnes. The church was later rebuilt under Pope Honorius I and restored several times. It remains one of the more intact examples of an ancient Christian basilica.
Its position on Via Nomentana puts it outside the central cluster of Rome’s best-known attractions. The quieter setting suits a visit focused on the church and its history.
Inside the church
Take time to look up at the ceiling and around the interior. The church contains artwork, a mosaic and Latin inscriptions dating to the late Roman period. A classical statue with a newer head is another detail to look for.
The basilica’s age is part of what gives the interior its character. Its architectural details reward a slower look, especially if you are interested in early Christian church design.
Underground areas and access
The visit can extend below ground to archaeological areas and catacombs, alongside a historical museum associated with the church. Access has been affected by construction work, and some areas have been closed at times. Confirm which parts are open before setting out, particularly if the underground visit is your main reason for coming.
There is an entrance fee for the catacombs, and photography is prohibited there. Allow time for the church itself as well as any underground areas you can enter.
