Williamstown/Point Gellibrand Light.
(Melbourne Australia)
History
The original lighthouse was constructed in 1840, right on the point of Gellibrand's Point. It is most likely Victoria's first navigational aid of any distinction, though an unlit beacon had been on the site since 1835. It also may have been the first harbour light of its kind in Australia.
In 1853, a Mr R. L. J. Ellery, the first Government Astronomer, commenced determining accurate local mean time, and established a time ball so that shipmasters to correct their chronometers "at the fall of the ball" at exactly one o'clock each day.
By 1934 the time ball had been removed. In this year the bluestone tower was extended by 30 feet with a circular brick tower on top. The extension was then painted with a coat of aluminium paint.
Between 1987 and 1989, the brick extension was demolished and a functional new replica time ball mechanism was reinstalled restored by the Point Gellibrand Rotary Club to commemorate the history of the site. This was officially opened in 1990.
The tower today is operated by a computer, which drops the ball each day at 1pm as it was in the 19th and early 20th centuries.
