For #MosaicMonday the flooded crypt of the Basilica di San Francesco in #Ravenna.

The Basilica dates to the 10th century and was built on a 5th century church. Due to Ravenna’s marshland and the subsidence of the ground's surface the crypt is permanently submerged by water and nowadays home of goldfishes.

The mosaics belong to the church of the fifth century AD. The crypt is believed to hold the remains of Bishop Neon, who lived in the 5th century.
