Tratalias

Tratalias lies inland in the Sulcis district of southwestern Sardinia. Its church of Santa Maria di Monserrato was begun in 1213, after the bishops of Sulci sought a safer residence away from the coast. Pope Honorius III formally confirmed the transfer of their seat from Sant'Antioco in 1218.

After the fall of the Judicate of Cagliari in 1258, the Pisan Della Gherardesca family held Tratalias until 1355. They retained their lordship even after the Aragonese invasion of Sardinia in 1324. The settlement later declined and was sparsely inhabited by the fifteenth century. The bishopric moved to Iglesias, a transfer formally recognized in 1503. Tratalias and Santadi formed a barony held by the bishop, while settlement in the district began to grow again in the eighteenth century.
