Name and Location

The Feu Postérieur “Croas Malo” (Breton: Tour-tan Kroaz Maloù) is a lighthouse located in Treffiagat, Finistère, Brittany, France. It serves as an active navigational aid operated by Phares & Balises.

Location

The lighthouse stands adjacent to a quiet residential lane, approximately 500 meters inland from the Bay of Audierne. The address is 4 Rue et Xavier Quideau, 29730 Treffiagat, France. The coordinates are 47°47′47″ N, 4°16′23″ W (decimal 47.796431, –4.273069).

Construction and History

The exact date of the lighthouse's construction is not recorded in public sources. It likely dates from the mid-20th century when dozens of minor range lights were standardized along the Brittany coast. The light appears on cadastral maps updated in 2013 and on national frequency records from August 2019.

Architecture and Materials

The structure is a freestanding masonry tower with a square shape and white color (unadorned). It stands at a height of 17 meters above ground level.

Light and Navigation

The lighthouse is classified as a major light by the French ANFR (“Agence Nationale des Fréquences”) database under reference FR:ANFR 207071. The specific flash pattern and range are not officially published but correspond to standard rear-range requirements.

Accessibility and Visiting

The site lies on private land, and the tower itself is fenced and not open to visitors. The best views of the lighthouse can be seen from Rue et Xavier Quideau or from nearby coastal paths. There are no visitor facilities available.

Notable Views and Landscape

• Treffiagat village offers a small museum of local fishing traditions, sandy beaches at Lesconil and Pors Carn, and coastal walking trails.
• Le Guilvinec's busy fishing port, famous for its daily fish auction, is just a few kilometers to the west.

Technical and Operational Details

The lighthouse is fully automated with no keeper's quarters or onsite staff. It does not have an AIS transponder or radar installation; it serves purely as a passive optical aid forming a rear range line in conjunction with its front light (“Feu Antérieur Croas Malo”).
