Situated on a little hill in the historic centre of the village, this castle was built under the government of Oldofredi, a local feudal family, in the 14th century, but its current name is more recent: in 1427 The Republic of Venice obtained this castle and then it was given to an important chieftain, Francesco di Bussone, called Carmagnola. It has a square plan with a central court, and in the past there was a deep defensive ditch with a drawbridge.
