Church of the Holy Trinity Saccargia (Basilica della Santissima Trinita de Saccargia)

Built 1112-1116 by Giudice Constantine I of Torres as thanksgiving after receiving a child. Entrusted to Camaldolese monks. Extended 1118-1120 by Pisan craftsmen. Frescoes painted late 12th century. Monks departed 1384. Continues as functioning church.

Giudice Constantine I of Torres and his wife Marcusa were childless. They visited the Camaldolese monastery, seeking the monks' prayers for a child. When their prayer was answered and a child was born, Constantine ordered the construction of a church as thanksgiving—not a small chapel but a basilica. He entrusted it to the Camaldolese monks, the very community whose prayers had been answered. Construction began in 1112 and was completed in 1116, when the church was consecrated on October 5 under Pope Paschal II. Between 1118 and 1120, Pisan craftsmen extended the building, adding the striking bicolour facade and the tall bell tower. In the late 12th century, an artist from the Umbria-Lazio region painted the apse frescoes—the only Romanesque wall paintings to survive in Sardinia.
