Chiesa di San Zeno (L.Corevi, Comune di Pisa)The church is located near Porta San Zeno, which in the thirteenth century was also called the Monetary gate because it is located near the mint of the medieval era. From the top of the walls we can seethe back of one of the oldest Pisan churches, San Zeno, documented from 1029. The restorations of 1972 made it possible to formulate some hypotheses on the origin of the building, which would seem the final of seven buildings, starting from the second century AD. The most evident traces of this process were found under the floor and consist of a 7th century triple apse building. The façade is preceded by a porch with lozenge and oculi decorations, typical of the Pisan-Romanesque style, supported by reclaimed columns and capitals. Above is the coat of arms of Archbishop Filippo de’ Medici. The sides were decorated with ceramic basins, today preserved in the National Museum of San Matteo. After its collapse in 1409, the bell tower was no longer rebuilt. The church is now owned by the municipality.
