The Anvil Point Lighthouse is a lighthouse located near Swanage in Dorset, southern England.

History[edit]

The lighthouse in its compound.

The lighthouse is built of local stone and was completed in 1881.[3] It was opened by Neville Chamberlain's father, then Minister of Transport. The lighthouse tower is twelve metres tall, the height of the light above the high-water mark is 45 m (148 ft). The light is positioned to give a waypoint for vessels passing along the English Channel coast.

Originally the light was illuminated by a paraffin vapour burner (PVB) set within a large (first order) revolving 14-panel dioptric optic.[4]

During 1960, the lighthouse was modernised and electrified (with a new lamp, powered by mains electricity, replacing the PVB). At the same time a smaller optic replaced the original lens array, which was removed and donated to the Science Museum.[5]

Anvil Point Lighthouse was fully automated on 31 May 1991 and is now monitored and controlled from the Trinity House Operations Control Centre at Harwich.[6]

The lighthouse had a 1,000 watt filament lamp with an intensity of 500,000 Candela. The lights range was about 19 nautical miles (35 km; 22 mi), but was reduced to 9 nautical miles (17 km; 10 mi) following a review of aids to navigation in 2010.[7]

In 2012, a LED lamp was installed above the rotating Fresnel lens to serve as the main light at Anvil Point; its character is, as it was previously, a white flash every 10 seconds.[3] (The old lens, though no longer in use, remains in place in the tower.)

The old fog signal was a 5-minute cannon. In 1960 this was replaced by an electric emitter. In 1981 new automatic equipment was installed, but the fog signal was discontinued in 1988.[5]

The lighthouse is near a visitor centre and is sometimes open to the public for tours. This area is a Site of Special Scientific Interest (SSSI).[8] Some of the old buildings have been refurbished as holiday cottages.
