Piazza Santa Croce in Gerusalemme
Hours: 7,00am to 1,00pm; 3,30pm to 8,00pm
The church was converted from a wing of the nearby imperial palace. Restored in 1144, when the Romanesque bell tower was added, and rebuilt in in 1743.
It contains two beautiful water stoops, a tomb by Iacopo Sansovino, a fresco by Antoniazzo Romano, a magnificent mosaic in the Chapel of St. Helena. In the Chapel of the Relics there are fragments from the Cross, a nail and two thorns from the Crown.
