The station was opened on 20 November 1939, on a new section of
deep-level tunnel constructed between and stations when the
Metropolitan line's services on its branch were transferred to the
Bakerloo line. It is named after a nearby pub built in 1803–4, originally called The Swiss Tavern and later renamed Swiss Cottage. The new station initially operated as part of a combined station with the Metropolitan line's adjacent sub-surface
Swiss Cottage station (platforms 1 and 2 were Metropolitan line and 3 and 4 were Bakerloo line), but the Metropolitan line station was closed on 17 August 1940. The Bakerloo line station was subsequently transferred (along with
St John's Wood and the rest of the Stanmore branch) to the
Jubilee line when it opened on 1 May 1979. The station was used extensively during
The Blitz of
World War II as an
air raid shelter. ==Connections==
