Southgate is a London
Underground Piccadilly Line station in Southgate. It is located between Arnos Grove and Oakwood stations and is in Travelcard Zone 4.The station is built in the Art Deco/Streamline Moderne design style using brick, reinforced concrete and glass and is one of the best known of the many stations Charles Holden designed for London Underground. The station building is circular with a flat projecting concrete roof. Externally, the flat roof of the raised central section appears, impossibly, to be supported by nothing more than a horizontal band of windows that provide daylight to the ticket hall.
