Wadjemup Lighthouse

Completed in 1849, the original 20-metre Wadjemup Lighthouse was Western Australia's first stone lighthouse and was built to provide a safer sailing passage for ships to Fremantle Port and the Swan River Colony.

A second and larger replacement tower was built on the same site in 1896. It is the fourth oldest extant lighthouse in Western Australia and was Australia's first rotating beam lighthouse. A shipwreck that was partly caused by poor communications and misunderstood signals from the lighthouse prompted the construction of Bathurst Lighthouse on the island in 1900.
