Built on the ruins of a construction from the 4th century, it has a square plan, with the nave pierced by a tower, resting on a vault and equipped with a deep semicircular apse. The entire construction is covered with stone slabs, with most of the material probably coming from nearby Ulpia Traiana Sarmizegetusa, the capital of Roman Dacia.
