Chiesa di Santa Greca

The church of Santa Greca is located on the outskirts of Decimomannu, a town known in Roman times as Ad Decimum Lapidem, an important road junction in the hinterland of Cagliari.

The title is mentioned in documents from the 14th century onwards, from which it appears that the monastery is much older, possibly already existing in the 9th century.

This shrine is a place of pilgrimage, especially during the annual feast in honour of the saint that takes place on the last Sunday in September. On this occasion, the faithful descend to the 'prison of St. Greca', a barrel-vaulted hypogeum chamber paved in earthenware, the precise date of which is unknown but believed to be ancient.

The chronology of its construction is uncertain due to a lack of documentation. The Proto-Romanesque building was largely rebuilt by 1792, sparing some original parts, particularly sections of the walls and the apse. The latter, facing south-east, follows a deep parabolic iconographic profile and overlooks the hypogeum where the saint is believed to have suffered martyrdom.
