Trevose Head Lighthouse is a lighthouse on Trevose Head on the north Cornish coast at grid reference SW850766 lying to the WSW of Padstow [1] and was sited here as there was previously no light from Land's End to Lundy[2] and would be visible from Cape Cornwall to Hartland Point.[3]

After completion of the first tower, it was determined that the light was under certain circumstances liable to be mistaken by mariners. A second lower light[4] was therefore proposed and constructed 50 feet in front of the first light, with a covered passage between them for use by the lighthouse keepers.[2] Only the first built 'high' light now remains.

The tower is 27 metres (89 ft) tall, and has a range of 20 nautical miles (37 km; 23 mi), but, on a clear night, you can just spot the light from Pendeen Lighthouse, over 35 miles (56 km) away.[citation needed]

Construction[edit]

Designed by engineer James Walker[4] the two original lights, 'high' and 'low', were constructed under the supervision of Henry Norris [4] by builders Jacob & Thomas Olver of Falmouth [5][2][4] with the Fresnel lens supplied by Henry Lépaute of Paris [4] and the lamp with 4 concentric wicks & frame manufactured by Messrs. Wilkins & Co. of Long Acre.[2][4]

The site was surveyed by order of the Trinity Board in July 1844 with a design submitted that November and approved February 1845. Building began in that May with the laying out of the road and contract entered into with the builders the next month.[2] During gales on 20-21 November 1846 scaffolding attached to the tower was blown away.[6]

The light was first lit on 1 December 1847.[4][7]

In 1882 the 'high' light was changed to an occulting light and the 'low' light put out of use. In 1912 the light was again updated and work began on installing a 36 feet long fog horn which came into service in 1913 and was itself replaced by a new horn in 1963. The lighthouse was automated and became unmanned in 1995.[8]
