Palazzo dell'orologio Torre del Conte Ugolino
Located on the north part of the Piazza dei Cavalieri, is the current home of the Library of the Scuola Normale Superiore. The building was altered a few times during its history - most of it was finished in 1605-1608, while the small bell tower on top was added in 1696.
