Canary Wharf Underground Station
Canary Wharf Underground Station is built in a hollow of the former West India Dock. It is intensively used, with more peak time travellers than those using Oxford Circus. Constructed using 'cut-and-cover' techniques, the station itself is entirely underground. The only elements of the building that are visible externally are the vaulted glass canopies above the entrances. The roof of the station - the building's 'lid' - has been landscaped as a public park, with grass, trees, seating, fountains and paths. On entering the station concourse from either the platforms or from surface level at Canary Wharf, the large size of this space makes a notable impact.
