We continued our pilgrimage to the Santi Quattro Coronati, church of the four saints. The identity of the namesake saints is lost to history, but their protective powers couldn't have been very strong, since the church was burned to the ground by invading Normans in 1084. For this reason, the church was rebuilt as a fortress, with incredibly thick walls, two sets of gates at the entrance, and a belltower that doubles as a defense post. There are some peeling frescoes on the walls, and a nice cloister out back still used as a convent.
