Troubridge Hill Lighthouse

Troubridge Hill Lighthouse stands on the cliffs of the peninsula's south-eastern heel, a tall, windowless tower of warm unpainted brick that looks quite unlike any other light in South Australia. First lit in September 1980, it was built to take over the main navigation duty from the 1856 lighthouse on Troubridge Island, whose low sandy platform had always been a difficult home for a light.

The tower's custom-made brickwork was no aesthetic whim: the interlocking design was chosen for its strength against wind and earthquake loading, and the result won an award from the South Australian Clay Brick Association. Because the light was automated from the start, the tower needed no windows and no keepers — just a lonely, elegant column above the swell of Investigator Strait.

The lighthouse grounds are a short detour off the road between Edithburgh and Port Moorowie, and the surrounding clifftops are a fine spot for watching ships entering Gulf St Vincent. The coast here is part of the Walk the Yorke trail, so you can also arrive the slow way, on foot along the cliff edge.
