Ancient remains of the prehistoric and protohistoric eras are the megalithic "Tombs of the Giants"; the "domus dejanas" (houses of the witches), tombs dug into the rock; and the "nuraghi". The nuraghi, truncated cone towers in huge stone and fortified dwellings of the earliest inhabitants, can be found all over the island. Phoenician and Roman remains have been found at Tharros and Nora; there are Roman relics at Porto Torres and Cagliari. The Gothic-Catalonian style thrived in the island under the rule of the Spanish House of Aragon.
 
The National Archaeologic Museum of Cagliari is the most important museum on the island. In Sanna, you can visit the archaeologic and ethnographic sections of the Sanna Museum and the Pinacoteca.
