Longstone Lighthouse is an active 19th century lighthouse lighthouse located on Longstone Rock in the outer group of the Farne Islands off the Northumberland Coast, England. Completed in 1826, it was originally called the Outer Farne Lighthouse, and complemented the earlier Inner Farne Lighthouse. The lighthouse is best known for the 1838 wreck of the Forfarshire and the role of Grace Darling, the lighthouse keeper's daughter, in rescuing survivors.
The site had a long history of need for a light. In the late 17th century Sir John Clayton, and later, in 1755, Captain J. Blackhead, requested a light for the island. Both were turned down because the authorities, the Elder Brethren of Trinity House, were unable to persuade affected parties to contribute to the maintenance of the light.
In the mid-1820s the welfare of shipping won over and it was agreed that a lighthouse be constructed. The lighthouse originally used Argand lamps, but in 1952 was finally electrified, and in 1990 became fully automated, and the keepers withdrawn. It remains in use today and is now monitored remotely from the Trinity House Centre at Harwich, Essex.
The lantern room at the top of the lighthouse used to contain an optic made by Chance Brothers of Smethwick. It was made in 1873 and was used for almost 80 years. The optic was made up from a number of Fresnel lens, which were used to increase the transmission of light from the lamp. The optic is now on display at Thinktank, Birmingham Science Museum.
