The General Post Office (abbreviation GPO) is a landmark building in Sydney, Australia. It is located at the western end of Martin Place (No. 1 Martin Place), between George and Pitt Streets. The main facade stretches some 100 metres down Martin Place. In 1996, as part of the disbursement of Australia Post assets by the Federal Government of Australia, the building was sold to private owners. It was subsequently refurbished and now houses shops, restaurants, hotel rooms, and the lobby of two adjoining tower blocks. Designed by colonial architect James Barnet, the building was constructed in stages from 1866 to 1891. The clock tower was demolished in 1942 to reduce the visibility of the GPO in case of an air attack on Sydney. It was rebuilt in 1964.
