Castle of San Michele

The 1990s excavations have revealed the remains of a rural church, probably of the early medieval period, upon which was built the castle in the 12th century to defend the city of Santa Igia, the capital of the Giudicato of Cagliari. The chronology however is still uncertain: the date of construction of the castle it is doubtful as it is not clear if the church, now part of the structure, had been built before or simultaneously the castle.
