Santa Costanza, c.1710-1730

Among the early Christian catacombs in northern Rome, beyond the walls of the ancient city, are those of the Sant’Agnese fuori le mura complex. It is here along the via Nomentana that St Agnes of Rome is said to have been buried after her martyrdom in the early 4th century AD, and where a basilica dedicated to her was later built by Pope Honorius I (625-638).
