The Circle Line of the London Underground became known as such in 1949. The Circle line was not built as a separate line, but was instead created by joining parts of the District and Metropolitan lines as a service. Only two small sections of track are unique to the Circle Line - a connecting section between Aldgate and Tower Hill stations and another connection betweenGloucester Road and High Street Kensington.
The Circle Line approximately outlines Zone 1 of the Underground and is the only line (apart from the two stop Waterloo and City Line) that is completely contained within it.
