The Church of San Gavino in Gavoi, dating from the 15th-16th centuries, is a magnificent example of the late Gothic Aragonese style and is distinguished by its three naves. A highlight is the 30-meter-high bell tower, topped by a sundial still intact on the south side. On the facade of the church, above the main door, is a striking Gothic-style rose window.
Several valuable works of art are preserved inside the church, including the finely worked wooden baptismal font, polygonal in shape with carving decoration dated 1706, supported by a marble basin and signed by Juan Maria Peddio and brothers. Reserving from the same period are the Baroque-style wooden pulpit, also richly worked and inlaid by Giovanni Battista Nonnis, and two confessionals. Behind the altar is an imposing wooden choir from the mid-18th century.
Inside the church are preserved the old bells dated 1586 and 1591. The old church clock is currently kept at the town hall.
