The Castle of Terrarossa is a majestic residence of the Malaspina family, built in the 16th century. Designed by Marquis Fabrizio Malaspina, it features a square plan with four bulwarks, although many parts of the original project were never completed. Situated along the Via Francigena, the castle has simple exterior façades made of river and stone pebbles.
The interior includes over 40 rooms, with spacious living areas and private apartments. In the past, it also housed a silkworm farm. Following restoration, the castle now hosts the tourist information office and is used for various events.
