Its charm lies in its archaic appearance and the simplicity of its forms, as well as the privilege of becoming the home of a work, every Christmas, unique in Sardinian and with very few other examples in Italy. The Romanesque church of Nostra Signora di Talia stands in the eastern part of Olmedo, overlooking the square of the same name. The name probably comes from the statue of the Madonna d’Italia, found during the 18th century among the ruins of Talia, a village that no longer exists. The church – also known as Nostra Signora di Ulumetu – has features that suggest it was built by Tuscan-Lombard workers, probably in the first decades of the 12th century. The materials used were limestone, reddish tuff and basaltic trachyte.
