On the hill called Bicocca of Arenzano, stands the Sanctuary of N.S.delle Olivette, whose original title of “Hermitage” was due to the presence, in the 12th/13th century, of a holy hermit living there, in a primitive chapel. The title Olivette derives from the presence, in the surrounding area, of several olive trees. The original chapel is surrounded by a balustrade, and encloses into a broad niche on the altar, the 16th century statues of the Virgin, the Angel and the Father among the clouds. The Sanctuary is linked to marine life, as testified by some bas-reliefs and the few remaining votive offerings, portraying boats in the middle of sea storms.
In the lateral gallery of the Sanctuary there’s the "Itinerario Marinaro", a permanent exhibition that retraces the history of the village of Arenzano, linked to the sea. The setting is designed by the “Amici di Arenzano” Association.
