Chiesetta di San Gavino a Mare

This tiny church sits dramatically perched on a limestone cliff above the sea at Balai beach near Porto Torres, and it's a serious pilgrimage site tied to the city's deep devotion to its early Christian martyrs. The coastline here is riddled with natural erosion caves, making the setting genuinely striking. Inside, the church holds relics or objects of veneration connected to those martyrs — so it's not just a pretty seaside chapel but a place with real spiritual weight for locals.
