Crouesty Jetée du Sud Lighthouse

Fl Red 4s🇫🇷Arzon, FROperational

Crouesty Jetée du Sud is a 6-meter tall square masonry tower located on the south jetty at the entrance to Crouesty harbor, near Arzon. It displays a red light with a single flash every 4 seconds. The tower, painted white with a narrow green horizontal band, features a gallery but lacks a lantern. The site is open to the public, but the tower itself is closed. This structure guides vessels navigating the southern side of the Arzon harbor entrance.

Why it matters: This light is essential for guiding vessels safely into and out of Crouesty harbor, particularly for the numerous leisure craft and local fishing boats that frequent this popular marina. It specifically delineates the southern edge of the harbor entrance, preventing groundings on the jetty.
