what is the lowest underground station in london
Hampstead tube station Designed by architect Leslie Green the station was opened on 22 June 1907 by the Charing Cross, Euston & Hampstead Railway. Located at the junction of Heath Street and Hampstead High Street, the name Heath Street was proposed for the station before opening: indeed, the original tiled station signs on the platform walls still read Heath Street. Hampstead is on a steep hill and the station platforms are the deepest on the London Underground network, at 58.5 metres (192 ft) below ground level.[2] It has the deepest lift shaft on the Underground at 55 metres (180 ft) which houses high-speed lifts. They were previously Otis lifts, but were modernised by the Wadsworth Lift Company, and again in 2014 by the small generic lift installer Accord. There is also a spiral emergency staircase of over 320 steps.
