A rare and valuable example of religious architecture that ‘combines’ two styles, Romanesque and Gothic, evidence of a crucial phase of artistic and cultural transition. The church of San Gregorio stands in the ‘upper’ part of Sardara, right in the historic centre and not far from the area of the Sanctuary of Sant’Anastasia, considered sacred since the Nuragic age. There are no documents attesting to its construction and the first documents that mention it date back to 1341, although it is assumed that it was founded by the Benedictine fathers in the first quarter of the 14th century. It was probably built by local workers, who were determined to go beyond the traditional Sardinian Romanesque style by inserting elements of the ‘new’ Italian Gothic taste.
