The Oratory is in Corso Garibaldi near the marina. It is perhaps a building of Medioevo although the original structure has been modified over the years by several restorations.
The interior has a single nave with a wooden confessional, a marble altar with wooden statues and several frescoes by Thomas and Matteo Biazaci from Busca, with life scenes of the Virgin Mary.

The Oratory today is home to the homonymous Confraternity of SS. Annunziata.
