Hampstead

Hampstead is a London Underground station in Hampstead, North London. It is on the Edgware branch of the Northern line, between Golders Green and Belsize Park stations. The branch's northernmost subterranean station, it is on the boundary between Travelcard Zone 2 and Zone 3.

Designed by architect Leslie Green, it was opened on 22 June 1907 by the Charing Cross, Euston & Hampstead Railway. As it is at the junction of Heath Street and Hampstead High Street, the name Heath Street was proposed before opening, and the original tiled signs on the platform walls still read Heath Street. Because Hampstead is on a steep hill, the station's platforms are the deepest on the London Underground network, at 58.5 metres below ground level; and it has the deepest lift shaft on the Underground, at 55 metres. Its high-speed lifts, originally manufactured by Otis, were modernised by the Wadsworth Lift Company, and again in 2014 by Accord.
