History

The first station in the area was a pilot station established in 1860 at nearby Harrington, assisting ships navigating the entrance of the Manning River.

Crowdy Head Light and quarters, 1902.

The current lighthouse is the last of five lighthouses of similar design designed and built by James Barnet in 1878-80, the other four being Fingal Head Light, Clarence River Light (now demolished), Tacking Point Lighthouse and Richmond River Light. The original light was a fixed white light from a 4th order catadioptric apparatus with an intensity of less than 1,000 cd. It was manned by one keeper.

In 1928 the apparatus was converted to a carbide lamp (acetylene gas), with an intensity of 1,500 cd. At the same opportunity the light was automated.

The pilot station was closed in the 1960s. In 1972 the light was converted to mains electricity.

In 2002 the 4th order Fresnel lens was sold on eBay in 2002 for $20,000, and is now on display at Sea Girt Light in New Jersey.[3]

Structure

Crowdy Head Light, detail of the lamp.

The circular tower is capped by an oversailing bluestone platform supported by shaped bluestone corbels. It can be reached by a metal stair from the concrete slab which forms the ground floor and foundation for the buildings. The tower walls of stone bricks taper off from a thickness of 19 inches (480 mm) at the base to 14 inches (360 mm) at the top.

A porch, roofed just above door height, connects the tower to a rectangular annexe, which originally contained a duty room for the keeper and a store for fuel

All the external walls of the structure are cement rendered and painted white. The platform is surmounted by a simple metal domed lantern which encloses the optical apparatus. A handrail at the platform perimeter is of white painted cast iron standards with wrought iron rails.

Site operation

The light is managed by Roads and Maritime Services (formerly NSW Maritime),[4] while the site is managed by the New South Wales Department of Lands.

Visiting

The grounds of the lighthouse are open, but the tower is closed.
