Tratalias

Overview and Geography

Tratalias is an agricultural municipality situated in the southwestern part of the Province of South Sardinia, within the Sulcis region and just inland from the Gulf of Palmas. The municipal territory includes the artificial basin of Monte Pranu (lago artificiale di Monte Pranu), created by damming the Palmas River in 1954.

History and the Abandoned Medieval Village

• Tratalias Vecchia: The historic medieval village (Tratalias Vecchia) grew around the ancient cathedral and was protected by the Castle of Tului built by the Judges of Cagliari. However, water infiltration and land subsidence following the creation of the Monte Pranu reservoir in the second half of the 20th century rendered the old houses uninhabitable. As a result, the population relocated to a newly constructed settlement (Tratalias Nuova) built on nearby hills. Today, the old center is undergoing tourism-focused revitalization and restoration.

• Historical Milestones: During the Middle Ages, Tratalias served as an important center and hosted the seat of the Diocese of Sulcis starting in the 13th century. The episcopal seat was officially transferred to Iglesias in 1503 by Pope Julius II via the papal bull Aequum reputamus.

Architecture and Landmarks

• Basilica of Santa Maria di Monserrat (Old Cathedral): Erected in the Pisan-Romanesque style between 1213 and 1282, this monumental church is built from limestone and trachyte. It features a tripartited lower facade, a rosette window, hanging arches on sculpted corbels, and an interior divided into three naves by arches and pillars. It serves as the spiritual centerpiece of the abandoned medieval village.

• Casa Spagnola: Built prior to 1655 and restored in the 17th century, this traditional Campidanese manor house features loggias, interior courtyards, and mud-straw bricks (làdiri), and now houses the Museo del Territorio Trataliese.

• New Church of Santa Maria di Monserrat: Located in the modern town center on Piazza Emilio Lussu, it temporarily hosts the sacred statue of the Virgin of Monserrat during the annual Sa festa Manna celebrations.

Economy

• Primary Activities: The local economy is grounded primarily in agriculture—producing cereals, wheat, vegetables, forage, vines, olives, and citrus fruit—alongside livestock breeding.

• Tourism: The municipality possesses strong tourism potential anchored by its stunning medieval historic center, the Pisan-Romanesque basilica, and nearby archaeological sites.
