The church of San Gemiliano stands north of the town, from which it is about five kilometers away. Built in the second half of the 13th century, it belonged to the vanished village of Sussua. The plan is rectangular, consisting of two side-by-side aisles with separate entrances and distinct apses; the aisles are separated by arches on pillars and covered by barrel vaults set by transverse arches. San Gemiliano differs from other similar ones built in the south of the island in the inversion of the ratios of the width of the naves and the width of the respective apses. In fact, in San Gemiliano the north aisle is greater. In the 17th century an open porch divided into three naves was added to the church; the sacristy and accommodation for the hermit, i.e., the guardian of the church, was added on the left side.
