About Kerprigent Lighthouse

Also known as: Kerprigent (Passe de l'Est Feu Postérieur)

The Kerprigent lighthouse, built in 1860, is a white, cylindrical stone tower 14 meters high. It stands 79 meters above sea level and emits a quick-flashing white light. The structure includes a conical roof and an attached one-story stone keeper's house. Its light is displayed through a window. The lighthouse is situated 2.9 km southwest of the Colombier light and is located off the Chemin de Kerprigent, west of Saint-Méen. The site is open to the public, but the tower itself is closed.

Why it matters: The lighthouse's quick-flashing white light is intensified on the range line, providing precise directional guidance for vessels navigating the coastal waters west of Saint-Méen. Its unique design, featuring a light displayed through a window, distinguishes it architecturally, and it continues the area's history of navigational aids that includes an ancient stone mill tower.
