Wolf Rock Lighthouse is on the Wolf Rock (Cornish: An Welv, meaning the lip), 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, England, United Kingdom. The fissures in the rock are said to produce a howling sound in gales, hence the name.
The lighthouse is 116m 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 the Cornish mainland and the Isles. The light is visible from Land's End by day and night. 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.
