Via Cavalca, the Campano and the Jew's house
The Campano tower, or of the Caciaioli, is a structure built for defensive purposes in the twelfth century, and later converted into a civil residence. In 1785, Grand Duke Pietro Leopoldo I ordered a bell to be placed at the top of the tower: every day the bell marked the hours of the study day for the nearby Sapienza, the University of Pisa.
The red building, located on the corner between Via Cavalca and Vicolo del Tidi, features two large pointed arches, remains of the church of Santa Margherita, mentioned from the eighth century.
