Old Ploumanac'h lighthouse, Lighthouse in Ploumanac'h, Brittany, France

The old Ploumanac'h lighthouse stands about 49 feet tall and is constructed entirely from pink granite, marking the entrance to the harbor along the Côte de Granit Rose in Brittany.

The original lighthouse was built in 1860 but was destroyed by German forces in 1944, and the current structure was completed in 1948 by architects Auffret and Hardion using local granite.

Known locally as phare de Mean Ruz, the lighthouse name derives from Breton language meaning red stone, reflecting the regional pink granite formations characteristic of this stretch of Brittany's coastline.

Visitors can view the lighthouse from coastal walking paths accessible from Perros-Guirec, crossing a small stone bridge to the rocky platform where the tower stands near the harbor entrance.

The Odorico mosaics belong to the 1948 tower by architects Auffret and Hardion, not to the 1860 lighthouse destroyed in 1944. Look for the narrow recessed channel running up the centre of the front face, a detail easily missed from the coastal path.
