The castle was originally built as a strategic defensive point to control the territory surrounding the city of Cagliari.
During the 14th century, it was converted into a fortified residence by the Carroz, a powerful noble family of Iberian origin.
The structure served as an isolation hospital (lazaretto) during the 17th-century plague epidemics.
The castle underwent significant restoration in the 1990s to adapt it into a public cultural space.
The surrounding park is part of a protected urban green area known as the Parco di San Michele.
Castello di San Michele is a 12th-century fortification located on the San Michele hill in Cagliari, Sardinia. It evolved from a defensive structure into a noble residence for the Carroz family and eventually served as a lazaretto during plague outbreaks. The site currently functions as a contemporary cultural center managed by the municipality of Cagliari. Its architecture features three surviving towers and a curtain wall surrounding a central courtyard. The interior galleries host rotating temporary art exhibitions and multimedia cultural events. The site offers panoramic views of the entire city and the surrounding lagoons. Excavations at the site have uncovered significant archaeological layers dating back to the Middle Ages.
