After Macquarie, subsequent governors and (after the establishment of responsible government in the colony) governments continued to regard Macquarie Street as the axis of an informal governmental and public precinct. The State Library of New South Wales, the Colonial Secretary's Building and the old Treasury Building, (now part of the InterContinental Hotel) are examples of such institutions. At the same time, as an elegant tree-lined boulevarde adjacent both to the commercial city centre and the green spaces of the Royal Botanic Gardens and the Domain, the street became Sydney's most pre-eminent residential address. In particular, the close proximity to Sydney Hospital and court buildings attracted leading barristers and doctors to set up chambers and surgeries along the street. In 1977, the New South Wales government built a new Law Courts Building at Queen's Square at the southern end of the street, to house the Supreme Court of New South Wales and the Sydney registries of the Federal Court of Australia and the High Court of Australia.
