維多利亞線
The present single-storey structure was built in the 1960s for the opening of the Victoria line on 1 September 1968 and is the entrance for all lines. When the escalators to the deep-level platforms were opened, the GN&amp;CR station building was closed. Its disused entrance remains and was refurbished externally in 2006 – it houses signalling equipment for the Victoria line.
