The church of Saint Agnes Outside the Walls is a titulus church, minor basilica in Rome, on a site sloping down from the Via Nomentana, which runs north-east out of the city, still under its ancient name. What are said to be the remains of Saint Agnes are below the high altar. The church is built over the Catacombs of Saint Agnes, where the saint was originally buried, and which may still be visited from the church.
