Cape Naturaliste, in the south west of Western Australia, is the site of a lighthouse which was activated in 1904.[1]

It is a 20 metres (66 ft) high cylindrical tower built of limestone that still uses its original first order Fresnel lens made by Chance Brothers. The light characteristic is "Fl. (2) 10 s", i.e. a group of two flashes every ten seconds, the focal plane is at 123 metres (404 ft) above sea level. Another precious lens optic is displayed there, the second order Fresnel lens of the Jarman Island Light, as well as the original Great Sandy Islands beacon. Both items were originally used on the Pilbara coast further north.

The lighthouse was constructed of limestone quarried from nearby Bunker Bay, which was also known as the "Quarries".
