Between 1908 and 1916 the Conservatorium of Music was created in adapted former Governor's Stables in the Western Domain. By 1916 there were of gardens/Domain. During the 1920s, cut and cover tunnelling impacted the Western Domain to create City Circle underground rail line. Between 1956 and 1959 Outer Domain land was taken by Sydney City Council to construct a car park (now the Domain Car Parking station), with the resultant loss of 47 relatively rare trees, and land. The parking station can be accessed via a moving footway from College Street, near St Mary's and other surrounding roads.
