The Roundhouse is a performing arts and concert venue at the Grade II* listed former railway engine shed in Chalk Farm, London, England. The building was erected in 1846–1847 by the London & North Western Railway as a roundhouse, a circular building containing a railway turntable, but was used for that purpose for only about a decade. After being used as a warehouse for a number of years, the building fell into disuse just before World War II. It was first made a listed building in 1954.
It reopened after 25 years, in 1964, as a performing arts venue, when the playwright Arnold Wesker established the Centre 42 Theatre Company and adapted the building as a theatre. The large circular structure has hosted various promotions, such as the launch of the underground paper International Times in 1966, one of only two UK appearances by The Doors with Jim Morrison in 1968, and the Greasy Truckers Party in 1972.
