The ancient church arose after the devastation of the plague of 1454. The indication on the portal (1477) confirms the completion date of the works and it might have been built on the site where the ancient parish church mentioned in the bull of 1186 by Pope Urban III to Bishop Gionata stood (some scholars hypothesize the foundation of the ancient church even in the 4th-5th century).
The patron is Saint Andrew the Apostle, a fisherman, and the dedication is significant for this place where the course of the Tagliamento maius flowed.
The temple was originally a single nave, with a square presbytery vaulted with a cross vault, but at the end of the 16th century, the two side aisles were added.
The interior is divided by wide arches supported by octagonal pillars, with a wooden roof supported by trusses. Above the portal, there is a pointed lunette with an almost illegible fresco of Madonna with Child seated on a throne, of 15th-century style not easily attributable (Bellunello?).
On the right pillar, there is a fresco of the Santissima Trinità by an anonymous 16th-century painter, follower of Bellunello and Pietro da San Vito. On the eastern wall of the southern nave, there is the fresco of San Martino a cavallo by an anonymous 16th-century painter.
On the first altar on the left (linked to a very ancient confraternity, perhaps from the 1300s) there is the altarpiece of the Purificazione di Maria by Giuseppe de Gobbis (1769).
The Sails
The frescoes on the vault of the main chapel depict Doctors of the Church on thrones with evangelists, prophets, and musical angels: they have been restored and attributed to Gianfrancesco da Tolmezzo, who almost certainly worked with a second master, particularly for the decoration of the apse walls, probably Pietro de Fadelo da Vicenza (early 16th century). For the second master, there is also a hypothesis for the young Pordenone, whose presence is documented in Cordovado in 1507.
