Description
In designing the Sydney GPO, James Barnet drew his inspiration from the Palazzi Communali of late Mediaeval and Renaissance Italy. The building is a key example of the Victorian Free Classical style. The style is seen in the symmetrical facade facing Martin Place, the prominent 70m high clock tower, the parapet concealing the roof, pediments (conventional and unconventional) highlighting the main entry, a ground floor arcade, piers treated as pilasters, and decorative elements on the skyline. The building's walls are constructed from Pyrmont sandstone, and the arcades have monolithic grey granite columns on massive bases and carved capitals. The building has a basement, ground floor, a mezzanine and three upper floors, and a later attic.
 
The GPO is recognised as possessing the greatest monumental stone street facade in Sydney, and the facade runs for an entire block. The GPO is the biggest and grandest post office in NSW and, with the Melbourne GPO, the most impressive in Australia. The Sydney GPO holds a key place in the Martin Place streetscape of central Sydney, and it has social significance for its lengthy association with postal services.
History
A post office first stood on this site in 1830, but owing to overcrowding a few decades later, a new building was needed. Colonial Architect James Barnet drew plans in 1865, and construction commenced the following year. Builder John Young did much of the work. Completion of this first phase of the GPO, fronting George Street, was celebrated in 1874. Several years later, to Barnet's design, the building was extended to Pitt Street. The tower stonework was completed in 1885 (the clock was completed in 1891) and the GPO's trademark colonnade along the northern (Martin Place) facade was opened to the public in 1887. The building was extended again in the 1890s, this time to designs by Barnet's successor, W. L. Vernon. Further additions followed in the 1900s, and additional new buildings were erected in 1927 and 1942. As a wartime precaution, the tower was dismantled in 1942 and re-erected in 1964.
 
The building reflects changes in postal technology, and its expansion illustrates the growth of the NSW postal service during the nineteenth and twentieth centuries. The building was also the 'centre' of Sydney, with all NSW mileages being taken from there after it succeeded the Macquarie Obelisk in Macquarie Place. Significantly, in the lead-up to Federation, the building was the venue for two Postal and Telegraphic Conferences in 1896 to discuss co-ordination and integration of colonial services. In 1900 another major conference at the GPO followed the Federation referenda, and a bill for Commonwealth control of posts and telegraphs was drawn up, which in 1902 became an Act.
 
The building was closed for safety reasons in the 1980s. Extensive alterations began in 1997, including a multi-storey hotel tower behind the main building, and the Commonwealth sold the property. The whole complex, including offices and commercial premises and a post office, opened in 1999.
Condition and Integrity
Most of original fittings still intact. Clock Tower restored in 1963 after being removed in 1942. (1978)

In the 1980s, the building was closed for safety reasons. In 1997 work began on extensive alterations, which included a 31-storey hotel tower at the rear. The Westin Hotel opened in 1999, and some hotel rooms along with commercial premises were opened in the GPO as well. Offices were also part of the huge project. The project saw restoration of elements including the postal hall and the grand staircase. A post office operates once again in the GPO. (December 2000)
