About Île Dupas Range Rear Lighthouse

The Île Dupas Range Rear light was established in 1907. Its square skeletal mast, standing 20.5 meters tall, supports a trapezoidal daymark painted bright orange-red with a black vertical stripe. This structure ensures visibility during daylight hours. At night, it emits a continuous green light, visible only when aligned with the front range light situated 625 meters to the south. The tower's focal height reaches 25.5 meters, and the light has a geographic range of 14.4 nautical miles. The site is open to the public, though the tower itself is closed.

Why it matters: This range light provides critical directional guidance, ensuring vessels maintain the correct course through the channel. The distinctive daymark offers a clear visual reference during daylight, complementing the night-time light signal.
