Things to see
Visitors can admire original frescoes, partly representing pagan themes, like the Proserpine myth; while the “newer” ones are dedicated to the Christian cult. In one room are also present traces of mosaics dated 3rd century AD.
Some of the rooms were transformed by Christians into an oratory and a beautifully decorated confessional was built during the 4th century.
A visit to this amazingly well conserved site will deepen your understanding of how Ancient Rome was built.
