London’s Only Lighthouse

(via Amusing Planet) On the north bank of River Thames, just across the iconic O2 arena (formerly known as the Millennium Dome), stands London’s only lighthouse. It was built in 1866 for the purpose of testing new types of lamps and lighthouse technology, as well as training prospective lighthouse keepers. The hexagonal brick tower with a traditional light at the top was part of the training school and workshop facilities that operated on this wharf.
