August 20, 2025, The Fisherman and the Mermaid Statues of Port-Haliguen

Two works by the German sculptor Karsten Klingbeil (1925–2016). The Berlin sculptor Karsten Klingbeil created this sculpture of a fisherman sitting on a lobster trap at the marina in Quiberon Port Haliguen, gazing out to sea. Karsten Klingbeil, of German descent, created it and donated it to the town. It is very personal, as the sculptor gave the fisherman his own features. He gazes across the harbor entrance at the sculpture of a beautiful mermaid who is just freeing herself from a fishing net.

Built in the 16th century, the chapel opposite Plouharnel Bay is listed as a historic monument. It was enlarged in the 18th century, damaged during the Revolution and World War II, and subsequently restored. The chapel houses beautiful furniture, the most notable of which is an alabaster relief depicting the Tree of Jesse. This 16th-century sculpture is listed as a historic monument.

Real racing boats are often moored here. Lots of speed, little comfort.
