Palazzo del Capitanio was once the seat of the Capitanio, one of the two Venetian rectors living permanently in Padova. In the middle of its façade (1598-1605) stands the Clock Tower. The clock, the first in Italy to show months, days, Moon phases and position of the Sun in the Zodiac besides hours, was created in 1437 by Giovanni delle Caldiere and is based on a 1344 project by Giovanni Dondi, nicknamed dell’Orologio (of the clock).
