The origins of the temple in St Hilary date back to the 12th century. It was dedicated to Saint Hilarius, bishop of Poitiers, who lived in the fourth century. Probably, however, it initially was dedicated to a Breton missionary and saint, Ilar or a native saint, Elian. Probably the oblivion of these saints led to the recognition of the church’s dedication to the bishop of Poitiers. In the fourteenth century, the church was enlarged by the southern nave, and in the sixteenth century by the western tower. In the 19th century, a renovation was carried out, during which windows and roofs were replaced and a porch was added.
The church consists of a rectangular nave and a narrower, short, rectangular chancel. From the south a side nave from the 14th century is adjacent to the main nave. It has the same length, but is topped with a separate gable roof. At the end of the Middle Ages, a four-sided tower was added to the western wall of the main nave. It has buttresses in the corners and it is topped with a parapet on corbels and battlement. The porch is a modern addition. The original window from the 12th century has been preserved in the northern wall of the presbytery. Also the chancel arch separating the nave from the presbytery is dated to the earliest period of the temple’s existence. Inside the church, tombstones from the fourteenth and fifteenth centuries have been preserved.
