San Piero a Grado

San Piero a Grado is a church in Pisa, Tuscany, Italy, in the eponymous frazione 7 kilometres west of the city center. The church is located where once was a now disappeared port of the Pisan Republic, where, according to the legend, St. Peter landed in Italy from Antiochia in 44 AD.
Archaeological excavations have shown the presence of a Palaeo-Christian edifice in the area, built over civil Roman structures, which was later replaced by a larger church in the early Middle Ages . The current construction, begun in the 10th century and renovated in the late 11th-early 12th centuries, has a basilica plan with a nave and two aisles. Unusual is the presence of an apses the facade, probably built after the crumbling of the facade due to a flood of the Arno River. The entrance is on the northern side.
