The church of Sant’Efisio is located inside the cemetery of Quartucciu. It was built in the late Romanesque period with limestone. The façade culminates in a gabled roof characterized by a single-light pointed bell tower. The two corner pilasters are connected by a continuous series of hanging arches resting on decorated corbels. In the center is the entrance portal surmounted by a cornice with a decorative denticulated motif. The interior of the building is a single rectangular hall with a wooden roof and chancel bordered by a marble balustrade.
