Located in Bauladu, the church dedicated to St Gregory the Great is of significant historical importance. Its construction, datable between 1205 and 1228, coincides with a period when Sardinia was the object of great interest on the part of the papacy. St. Gregory the Great himself, during his pontificate (590-604), wrote no less than 41 letters concerning the island, thus providing a valuable source of information on the early Middle Ages in Sardinia. The building is distinguished by a remarkable portal, adorned with a limestone relief in Gothic-Catalan style dating back to the late 16th century. This artistic element, which depicts the Virgin and Child between two angels, is the subject of a curious local legend: it is said to be the work of the mythical 'Damas Cugurras', three women of the village originally from Santa Barbara di Turre. Inside the church, you can admire a polychrome statue of the Madonna of the Snow, a 16th-century work probably of the Spanish school.
