The Torre del Campanon dominates the summit of the Colle delle Capre with its height of about 34 metres. Its foundation dates back to the late Romantic period, corresponding to the first phase of construction.
The second phase is dated back to the late medieval period. The fortified complex had to undergo restoration in 1406, under the government of Francesco Foscari.The third phase, dating from the second half of the 16th century, corresponds to the elevation to the current level that has incorporated the Ghibelline battlements.
The walls were repaired after the collapse of the bells following a violent storm in 1579, narrated by Cambruzzi, which caused the breaking through of the wooden structures, floors and stairs. On this occasion the bells were redone, of which the bigger «increased of 800 pounds» was placed on the castle tower, while the smaller was placed on the Torre dell'Orologio.
In 1676 the large bell weighing 3600 pounds was replaced with the current 3800 pounds, made by Antonio Trabucchi of Bormio, as attested by date and name engraved in bronze.
It was the only one not requisitioned by the Austro-Hungarian troops during the invasion of 1917-18. With the disappearance of the castle’s strategic and defensive function, culminating in the suppression of the castellan’s charge in 1519, The Torre del Campanon has assumed a symbolic function for the city with the sole purpose of warning the citizens of fires or danger situations.
