at St James, built to link with the proposed Eastern Suburbs railway have never been used for train movement although they were, along with the section of tunnel built to connect with Circular Quay, used as air raid shelters during World War II. After 1956 and the opening of Circular Quay station, St James and Museum suffered from reduced passenger usage and peak hours are now only a shadow of those in earlier years. In the 1960s an outdoor café was constructed behind (north-east) of Museum Station entry building, by Sydney City Council. Design of the café and landscaping were the work of Ilmars Berzins, SCC landscape architect. Although affected by reduced maintenance spending and unsympathetic additions, both stations have retained much of their original detailing and character. Design Designed by John Bradfield in the Inter-War Stripped Classical architectural style, the station comprises two platforms, each long by wide, under an arch with span . Museum's signage and cream tiling with maroon highlights are reminiscent of a typical London Underground tube station of the era, however its layout of central tracks under a grand arch are more in keeping with older stations of the Paris Métro. Until the construction of the Airport Line in the 1990s, it was the only underground station in Sydney without an island platform. It is a companion to St James station, both opened at the same time and use a roundel design on their station signage that is similar to the one used on the London Underground. The station opened on 20 December 1926 with the opening of the eastern city line from Central to St James. It became part of the City Circle loop on 22 January 1956. The main entrance to the station is located at the corner of Elizabeth and Liverpool Streets. Another entrance featuring a sandstone façade is located on the corner of Liverpool and Castlereagh Streets. This entrance sits at the foot of the District Court of New South Wales' Downing Centre, formerly the site of the Mark Foy's department store. Other entrances are also located on three corners of the intersection of Elizabeth and Bathurst Streets. All exits flow into one of two concourses at the station. The main concourse is the southern one, located near the Elizabeth and Liverpool St intersection. The toilets, station office and lifts are all located in this concourse. The northern concourse is located
