Basilica of St. Peter in Chains
The Basilica of St. Peter in Chains was built in the fifth century A.D. with the help of the Empress Licinia Eudoxia. The Basilica takes its name from the fact that inside there are preserved the chains that, according to tradition, were used to bind and immobilize St. Peter during his imprisonment. A series of excavations has revealed that, before the construction of the Basilica, there were more old buildings with mosaic decorations. The Basilica has a courtyard with a small fountain which has a hexagonal plant.
