Beyond the Contrada Cà Bongiasca there are the ruins of the castle of Mancapane, which stands in a dominant position over the Grumello castle and the valley. Built in the second half of the 13th century, it consists of a tower and a fortified enclosure, so it had to perform both guard and signaling and defense functions.
