The Ermita Hill is geographically located at the center of the town of Casiguran.It provides an enchanting view of the entire Poblacion, the dark blue coast of Casiguran Bay and the barrios nearby. Aside from its magnificent landscape, Ermita Hill is known as a sacred dwelling for religious activities by devotees of the Miraculous Mother Mary, of whom a life-size statue is situated in a grotto on top of the hill. The native folks believe that through the intercession of the Our Lady of Ermita, the town is oftentimes saved from devastating typhoons and storm signals. Locals said that even the news reported an incoming storm, it does not directly hit the town. Moreover, under the Spanish rule, a Watchtower was built just a few steps at the back of the chapel to guard the town against possible attackers.
