Colchester Reef Lighthouse

Fl Red 4s🇨🇦Town of Essex, CAOperational

A cylindrical stone pier, constructed in 1885, supports a square steel skeletal tower that stands 12 meters tall. This structure, first lit in 1885, emits a single red flash every 4 seconds from a focal height of 22 meters. The station was established in 1885, succeeding a lightship that had been in place since the 1870s to mark the southern edge of Colchester Reef. In 1954, a second lighthouse was built, incorporating a cantilevered design that provided a helicopter landing pad. This lighthouse is located approximately 6 kilometers south of Colchester within the Town of Essex.

Why it matters: The Colchester Reef light is essential for guiding vessels around the reef's southern edge, ensuring safe passage for traffic heading toward Kingsville and other nearby ports.
