Portland Breakwater Lighthouse

Portland Breakwater Lighthouse is a cast iron maritime beacon on the Isle of Portland in Dorset, standing about 22 meters tall above the harbor waters. The structure features a hexagonal design with a central cylinder, a viewing platform, and a lantern room where the light mechanism operates.

The lighthouse began operations in 1905 to guide ships through Portland Harbour waters and provide navigation assistance. Trinity House managed the facility with resident keepers maintaining it until automation systems replaced human operators in the late 1960s.

This structure remains active as a navigation aid using modern LED technology to guide vessels through the harbor. Visitors should know it functions as a working beacon and access may be limited due to its operational status.

The original optical equipment from this beacon is preserved and displayed at Weymouth Museum, allowing visitors to see the historical light technology that once operated here. This artifact shows how lighthouse technology worked before modern automation changed everything.
