In World War I, about 1,300 houses were damaged by Zeppelin raids. By the 1920s, it had become a built-up and thriving urban industrial area known for manufacturing neckties and for its Thermos factory. During the Blitz of World War II, Leyton suffered as a target because of its proximity to the London Docks and Temple Mills rail yard. The yard (named after an ancient mill owned by the Knights Templar) is now reduced in size as part of it has become a retail park 'Leyton Mills', whilst the rest has been renovated to serve as a depot for high-speed Eurostar trains.
