Museum of the Tratalia Territory

In the medieval village of Tratalias, the Territorial Museum offers guided tours of the museum and the 13th-century Pisan-Romanesque Cathedral of Santa Maria di Montserrat. Tratalias appears like a village distant in time, wrapped in the untouched charm of its millennia-old history. Established overlooking the Gulf of Palmas around the year 1000 (like its current population), it reached its peak as an episcopal seat during the Pisan and Spanish eras and maintained a prominent role until the 19th century. The original village was abandoned in the 1980s, after the construction of the artificial lake of Monte Pranu, whose seeping waters made the houses uninhabitable. The new village arose a few hundred meters away.

The ghost town of a few restored stone houses will transport you to the enchanting atmosphere of ancient Tatalia, once enclosed by three Baroque arches—two of which are still intact—perhaps the ancient entrances to the citadel. At its center is the former Cathedral of Santa Maria di Monserrato, built between 1212 and 1282, the seat of the Diocese of Sulci from 1218 to 1503 after the abandonment of Sant'Antioco and the coastline, threatened by Saracen raids.
