Slime Road Range Rear Lighthouse
Location & Light Range
About Slime Road Range Rear Lighthouse
The Slime Road Range Rear light, established in 1914, guides vessels navigating westward out of Gloucester Harbour. The current square, skeletal cast iron tower stands 8 meters tall and was built in 1941. It features a lantern, gallery, and a rectangular daymark with vertical slats. Instead of a traditional lens, its focal plane at 16 meters emits a continuous blue light using vertical neon tubes, providing precise navigational guidance. The tower's black exterior is visible from Beachey Road, though the operational station is located within a British Army base and is not accessible to the public.
Why it matters: This range light is critical for outbound vessels using the marked channel from Gloucester Harbour. Its unique illumination method using neon tubes highlights a modern approach to maritime signaling within a restricted military zone.
