The imposing castle, which was founded in 1374 and served as a military fortress until the end of the 18th century, subsequently fell into disrepair throughout the 19th century. It owes its present appearance to the Derossi family, who acquired it in 1903; in 1991 it changed hands when it was purchased by the sculptor Villi Bossi and his wife, who renovated it and used it as their home for more than 30 years. Since March 2026, the castle has been owned by Culture Arti e Saperi S.r.l., a company funded by the AlessioGe Foundation, which has set itself the aim of enhancing and preserving the building and making it an integral part of life in the small town of Muggia.

The castle is affiliated to the Consortium for the Protection of the Historic Castles of Friuli Venezia Giulia and can be visited by reservation.

Although the castle is not always open, the town of Muggia is certainly worth a visit.
