Faro de Cabo San Agustín, Maritime lighthouse in Coaña, Spain.

The Faro de Cabo San Agustín is a lighthouse on the Asturian coast near Coaña and sits on a headland overlooking the estuary. The facility consists of a tower with lighting equipment that helps guide vessels through this coastal area.

The present lighthouse entered service in 1975, replacing a beacon mounted on a 5.5 m round stone tower with a gallery built in 1945 to mark the harbour entrance. That older tower still stands in front of the new lighthouse at the mouth of the Navia river.

The lighthouse is known locally as the Faru de Ḷḷuarca, using the Asturian name for the nearby town of Luarca. It stands beside the Ermita de San Agustín, the chapel that gives the cape its name, and the old 1945 beacon tower, 5.5 m high with a gallery, still stands in front of the new tower.

Visitors can explore the area around the lighthouse and enjoy views of the coast and sea. It is best to visit during daylight hours to see the landscape and estuary clearly.

The 5.5-metre stone tower built in 1945 to mark the port entrance still stands in front of the current lighthouse, a rare case of an old beacon kept beside its replacement. The present tower, 25 metres tall, carries two black horizontal bands on white.
