The Church of San Paolo a Ripa d'Arno is at the edge of Pisa's historic center by the Arno River. It was founded in the early ninth century and enlarged in the eleventh and twelfth centuries in Romanesque style similar to the Duomo. The exterior uses some Roman stones and inside is a second century Roman sarcophagus used as medieval tomb. There's an eleventh century Romanesque oratory and a twelfth century convent by the church.
