The rural sanctuary of San Costantino sits on the Monte Isei, on the edge of Sedilo. You can admire the vast panorama from the church as far as the Omodeo Lake.
The sanctuary can be accessed through two entrances, one with a monumental arch with single fornix displaying a Latin inscription dedicated to the saint: “CONSTANTINO · MAX(imo) · AVG(usto)”. Inside the area cordoned off with high walls, sa corte, we find not only the church but different buildings to welcome pilgrims and horses used during the Ardia, the horse race in honour of the saint.
Naming it after the saint who guaranteed religious freedom by stopping the Christian persecution, comes from the Byzantine era; indeed, the XVI-century church appears to have been built on top of a pre-existing building dating back to the VI century. In turn, the Catalan-Gothic building underwent changes which involved almost its entire reconstruction in the XVIII century and the one that followed.
The imposing building is laid out on a three-sided room barrel vaulted with side chapels and rib cross-vaulted presbytery, left over from the Catalan-Gothic building.
The red trachyte facade displays parameters of the Eighteenth century and a pillar of the central nave shows the year its renovation was completed: 1789. It has a curve-shaped pediment end point and bell gable on the left side. The smooth facade houses the only access portal crowned by semi-columns and triangular gable, flanked by two niches with quadrangular light on top.
