The deepest subway station in the world is located in?
Kiev
London
Portland
Pyongyang
Arsenalna  is a station on Kiev Metro’s Sviatoshynsko-Brovarska Line. The station was opened along with the first stage and is currently the deepest station in the world (105.5 metres (346 ft)). This is attributed to Kiev’s geography where the high bank of the Dnieper River rises above the rest of the city. Also unusual is the station’s design, which lacks a central concourse and is thus similar in layout to stations on the London Underground.
