About Middle Channel Rock Lighthouse
Middle Channel Rock lighthouse, built in 1966, is a 19-meter cylindrical structure situated on a reef 1.4 kilometers south-southeast of St. Ann's Head. It supports a round aluminum lantern housing. The lighthouse emits a single green flash every 7 seconds, visible for 12.9 nautical miles. This navigational aid marks the main channel defined by the Watwick Point Range. In September 2024, the lighthouse was reinforced by enclosing its base in a steel sheaf. While the site is accessible by boat, the tower itself is closed to the public.
Why it matters: This lighthouse is essential for safe navigation through the main channel defined by the Watwick Point Range, warning vessels of the submerged Middle Channel Rock reef.
