Cabras appeared in the 11th century, when the town of
Tharros was abandoned due to raids from North African pirates. The inhabitants first settled near the castle, scant remains of which can be seen near the parish church. Under the
Giudicato of Arborea it had some importance as the court of the
giudice (duke) was held in its castle. After the fall of the
giudicato, it was ruled by several feudal lords. In the 19th century it was included in the province of Oristano, until being annexed in 1859 to the
province of Cagliari. Cabras returned to Oristano in 1974. ==References==
