Remains of a medieval church discovered under St. Mark's Square in Venice.

The remains of the church of San Geminiano have appeared during some excavations. During the Middle Ages, the church was one of the most important places of worship in the city. Excavations began months ago after finding some remains while beginning the restoration of the stone blocks used for the square's floor, damaged by rising waters in recent years. The church is important not only because it may be the oldest in Venice, but also because it was a church to which the Doges of the first centuries of the Republic of Venice were very devoted.
