San Lorenzino is the older of Orco Feglino's two parish churches, perched on the ridge just below the castle. The fabric is twelfth to fourteenth century, in the simple Ligurian Romanesque manner — squared stone, a single nave, a low pitched roof, and a square campanile with two tiers of paired arched windows.
The interior is modest and usually closed outside Sunday services, but the exterior and the surrounding terraced ground are worth the climb on their own. The church sits in one of the most photogenic corners of the comune, with the Aquila valley falling away below and the limestone walls of the Finalese rising behind.
