Castello Siviller o Casa Forte

---

Castello Siviller, also known as Casa Forte or the Castle of Villasor, is a well-preserved fortified residence located in the historic center of Villasor, Sardinia.

Built in 1415 by the feudal lord Giovanni Siviller, it was designed both as a noble residence and as a defensive stronghold to protect the area during a period of political instability following the conflicts between the Aragonese and the Judicate of Arborea. The castle later passed to the powerful Alagon family and became the center of the Marquisate of Villasor.

Over the centuries, it served a variety of purposes, including a barracks, prison, and school, before eventually being restored by the local municipality. Today, Castello Siviller is one of the finest examples of Aragonese Gothic architecture in Sardinia. Its distinctive fortified design, inner courtyard, and historic rooms make it an important cultural landmark that now hosts exhibitions, conferences, and community events.
