The Western Channel Pile Light, also known as the West Wedding Cake due to its shape, is an active pile lighthouse located on Sydney Harbour, New South Wales, Australia, off Georges Head, Mosman.

[2] It was constructed from concrete bottom (originally known as the "gas house"), supported by twelve piles,[3] with a copper top and a wooden stakes skirt.

[4] The lighthouse was due for replacement in 2007, and a budget was set, but on 12 December 2006 it collapsed,[4] as one or two of the supporting piles broke.

[3] Sydney Ports Corporation employed Waterways Constructions to reconstruct the lighthouse.

[5] The new tower was designed to look as similar as possible to its predecessor, using the salvaged and renovated lantern house, and a new lower section.
