This temple is a municipal building belonging to the city forum. It is one of the few buildings of religious character preserved in a satisfactory state. Despite its name, wrongly assigned on its discovery, the building was dedicated to the Imperial cult. It was built in the late 1st century BC or early in the Augustan era. Later it was partly re-used for the palace of the Count of Corbos.
Rectangular, and surrounded by columns, it faces the front of the city’s Forum. This front is formed by a set of six columns ending in a gable. It is mainly built of granite.
