The Church of San Paolo a Ripa d'Arno, formerly called ''Duomo Vecchio'' (old cathedral) on account of the function it fulfilled before the completion of the Church of Santa Maria Assunta in the Field of Miracles, was founded between the 9th and 10th centuries.
In subsequent centuries it was enlarged and enriched. A wonderful example of Pisan Romanesque architecture, the church has recently been restored and brought back to its essential features. The grand interior features a nave and two side aisles separated by imposing granite columns topped by capitals decorated with archaic figures.
The church contains the tomb of the 12th century scholar Burgundio, with a reused Roman sarcophagus.
It is open to the public during mass.
