‘In 1934 the Gaumont Palace opened at no. 206 King’s Road, designed by W.E. Trent and E.F. Tulley with a capacity of 2,502. It became the Gaumont by 1946, and the Odeon in 1963. It closed in 1972 and was converted into a department store for Habitat, which incorporated in the complex a new Odeon seating 739 which opened in 1973. It closed in 1981 and reopened 1983 as the Chelsea cinema.’
