General Information

The design for the Sundial was initiated by an architectural competition for the Town of Cottesloe, which sought an appropriate monument to commemorate the Australian Bicentenary. The project was built over a seven year period with extremely limited funds, and relied upon the generousity and voluntary contributions of many.

The Sundials equatorial form is derived from the sundials in Jaipur, India, createdby the Maharaja dei Singh in the 18th century. The two engraved dials (shadow plates) allow an accurate reading of the time to be taken throughout the year.They are separated by a narrow walkway , and are constructed of limestone blocks capped by pre-cast concrete to give a sharp shadow line.

Unlike the Jaipur sundial the shadow plates on the Cottesloe Sundial are engraved with equation of time curves. These curves accommodate the 4 degree and 17 second difference in logitude between the sundial at Cottesloe Beach and the meridian of West Australian Standard Time at Kalgoorlie. They convert apparent  solar time to Western Solar Time.
