Wolf Rock Lighthouse is on the Wolf Rock, Cornwall, a single rock located 18 nautical miles (33 km; 21 mi) east of St Mary's, Isles of Scilly and 8 nautical miles (15 km; 9.2 mi) southwest of Land's End, in Cornwall, United Kingdom. The fissures in the rock produce a howling sound in gales, hence the name.
The lighthouse is 41 metres (135 ft) in height and is constructed from Cornish granite prepared at Penzance, on the mainland of Cornwall. It took eight years, from 1861 to 1869, to build due to the treacherous weather conditions that can occur between Cornwall and Scilly. The light can be seen from Land's End by day and night, and is almost exactly halfway between the Lizard and the Isles of Scilly. It has a range of 23 nautical miles (43 km; 26 mi) and was automated in 1988. The lighthouse was the first in the world to be fitted with a helipad.
Situated between Cornwall and the Isles of Scilly, the Wolf Rock is a small plug of phonolitic lava formed during the early part of the Cretaceous period and is unlike any rock exposed on the Cornish mainland.
In 1791 Lt Henry Smith obtained permission from Trinity House to build a navigational mark on the rock. He built a 6.1 m (20 ft) high wrought iron daymark, 10 cm (4 in) in diameter and supported by six stays and a metal effigy of a wolf was placed on top. By 1795 the daymark was washed away. In the late 1830s John Thurburn built a beacon, which was completed on 15 July 1840, and in November of that year was wrecked by storms when the pole and globe on its top were washed away and not replaced until 1842 but they were once more washed away in a storm on 9 October 1844. Trinity House engineer James Walker constructed a 4.3 m (14 ft) high cone-shaped beacon, which took five years to build. Made of iron plates and filled with concrete rubble this was completed in 1848, it can still be seen next to the lighthouse. In July 1861, engineer James Douglass surveyed the rock and Walker started to build the lighthouse the following March, based on Smeaton's third Eddystone Lighthouse. Walker died in October 1862 and James Douglass was appointed engineer-in-chief to the Trinity House, William Douglass, the younger brother of James became resident engineer.:ch4 Completed on 19 July 1869, the light first shone in January 1870 and in 1879 it was reported that the light flashed red and white. In 1972 it became the first lighthouse in the world to be fitted with a helipad and the lighthouse became automated in July 1988.

At the close of the proceedings, the Commission having been informed by Mr. Pearce, agent to Lloyds that the exertions of the Trinity Board at the Wolf Rock had been crowned with success in the erection of a cast iron beacon, which had been completed only the preceding night, embarked on board the steamer accompanied by Mr. Pearce, to inspect it, when they expressed their decided approbation of the manner in which the work had been accomplished. The rock was at half tide; and the base of the beacon, which 18 feet in diameter, is about 7 feet above low water, spring tide. It is a cone composed of 10 courses of 2 feet 2 inches and an eleventh coarse of 3 feet, giving about 23 feet perpendicular height - This is surmounted by a strong oak mast of 34 feet, 11 of which are imbedded in the cone A ball of copper hoops, of 6 feet diameter, crowns the whole, giving a total elevation of 53 feet above low water and about 35 feet above high water at spring tides; and although nearly three leagues off, it is distinctly visible from the western land. The Beacon is painted read and white, in horizontal stripes.
