The oratory is located down near the port, in the eastern part of the town. Dating back to the 13th century, it was built in 1287, as indicated by the walled courtyard of the ancient bell tower. Originally named after San Giorgio, the building was amplified in the 16th century in the name of San Rocco, during the plague of 1584.
Built in the baroque style, the façade is dominated by a statue of Sant’Erasmo, whilst the interior consists of a lone aisle and four side chapels. The oratorio houses various important paintings, such as that of the Madonna with Child and of San Giuseppe with Santi Egidi and Antonio, painted by Domenico Fiasella, who was otherwise known as Sarzana.
The oriental style tower is topped with a versatile cupola.
