The Domain and Royal Botanic Gardens are some of the most important open spaces and parkland in Australia’s urban places. The 29 hectares of gardens are surrounded by 51 hectares of parkland including the Sydney Domain. The gardens are traditionally divided into 4 sections the Middle Garden, the Upper Garden, the Lower Garden and the Garden Palace Grounds. They were officially recognised as a botanic gardens in 1816 and while it only became the ‘Royal’ in 1959. The site is one of the world’s oldest colonial botanic gardens and one of the most important botanical sites in the Southern Hemisphere (only Rio de Janeiro is older). The area attracts around 4 million visitors a year.

The Dictionary of Sydney states that the gardens reflects:
the changing styles of ‘public gardens’ – from the utilitarian beds that provided the necessities of life in the early years, to the emerging styles associated with new ideas about landscape gardening for visual effect, to the overwrought overkill of Victoriana, with statues, urns, terraces, ponds, plinths and obelisks at every turn, through to the contemporary acceptance of the validity of ‘native’ flora as a legitimate focus in a public garden.
The Botanic Gardens were the site of the first government farm in the colony of New South Wales in 1788 (Middle Garden) and called the Governor’s Farm in 1792. Governor Phillip ordered the cultivation of 20 acres in 1788 and the area was part of Governor Phillip’s private reserve. The original farm furrows are evident in the alignment of the longitudinal beds of shrubs. The Governor’s Domain was one of the first pleasure grounds in the colony established in 1792 by Governor Phillip.

There were some private land grants on the eastern side of Farm Cove (1800-1807) which were resumed under Governor Bligh when carriage roads were built around Bennelong Point and Farm Cove in 1807. The main botanic farm function was transferred to Rose Hill at this time under Governor King. The Royal Botanic Gardens Trust states that in 1810
The new Governor, Lachlan Macquarie, terminate[d] leases and embarks on wall and fence building to re-establish the Domain as the Governor’s private parkland. His walls and rules [were] flouted.
The gardens link the oldest surviving group of Governor Macquarie period buildings in Australia along Macquarie Street (1810). There is also Governor Macquarie’s landscaping of the Domain with a gate and sandstone wall. The wall now separates the Lower and Middle Garden, was used to protect the garden from the harbour and built between 1812 and 1816. In Governor Macquarie’s time (1816) Mrs Macquarie Road was completed around the Domain to Mrs Macquarie Point.
The work of the gardens illustrates the associations with 18th century European scientific world of Sir Joseph Banks, Sir William Hooker and others. The gardens are Australia’s oldest scientific institution (1816) for botany and horticulture. In 1821 Superintendent Charles Fraser, a botanist, was appointed to develop the gardens along scientific grounds for the first time. Fraser accompanied John Oxley on his inland journeys and brought back plant specimens.
In 1825 Governor Brisbane extended the garden west of Farm Cove for an experimental garden to acclimatise Australian plants for export and imported plants. Colonists were interested in ‘exotics’ and brought many of them with them and were added to the garden plant collection. In 1829 grape vines were planted that became important in the foundation of the Australian wine industry.
In 1831 Governor Bourke opened the roads and paths for general access despite conservative opposition.

By the 1850s military, sporting and ceremonial events became common in the Domain. The area was the home of first class cricket in New South Wales from 1857 to 1871 and the first interstate match was held in the Domain in 1851 when NSW defeats Victoria. There were the first swimming championships in 1846 and a gymnasium (public playground).

In 1837 construction commenced for the new government house in the northern section of the Domain. It was completed in 1845. The area was the site of the Australia’s first zoo, an aviary in 1860 which was expanded into a larger facility with a monkey house in 1880. Eventually the zoo was relocated to Moore Park in 1883.

The Domain and gardens were the site of the 1878 International Exhibition and the Garden Palace (1879) which burnt down is spectacular fire in 1882, was the first exhibition in Australia featuring arts and industrial displays. The Garden Palace was located between the Conservatorium of Music (formerly the Government House Stables) and Macquarie Street. The site is the highest point in the garden and was originally surrounded by a paling fence for grazing the governor’s stock. The Central Depot in the gardens were the kitchen gardens for government house (Bridge Street, then Macquarie Street) from 1813 to 1870 and still has a rare glasshouse.

The sandstone wall adjacent to the Opera House with stone steps and iron railing is the northern boundary of the garden. The cliff wall was built in 1880 enabled the extension of Macquarie Street and is known as the Tarpeian Way. It provides a dramatic backdrop to the Opera House forecourt and gets its name from the famous rock on Capitoline Hill in Rome where prisoners were hurled to the deaths in ancient times. What are now the Opera House iron gates, were originally the Governor’s private gates, and built in 1870.
The Lower Garden was reclaimed from Farm Cove between 1848 and 1879 when the seawall was constructed with stone from the old government house in Bridge Street. This work extended the garden’s pleasure grounds with curving pleasure walks and plantings.

In the Domain the Hospital Road gate lodge and gate were built around 1865 and the Victorian gate lodge house was built on the eastern side of the garden. The Victorian herbarium building was constructed in 1899 and adapted as the visitor centre in 1982.
The Domain was quite extensive at one stage and successive governments have taken bits of it for various cultural institutions – Art Gallery of New South Wales (1885+), the State Library of NSW (1910+), Government House (1836+), Opera House (1966+), and Conservatorium of Music (formerly Government House Stables, 1816 and CoM, 1916+) – and oil tanks for the Navy in WW2.
The Domain has been a site of decent by the Sydney populace and the Dictionary of Sydney states:
The Domain has also had an important history as a ‘soap box’ arena, like London’s Speakers’ Corner in Hyde Park. ‘Soapbox Sunday’ may well go back into the late nineteenth century: in 1878, Baptist pastor Allen is reported to have gone there to speak on Irish Home Rule, after a riot in nearby Hyde Park.
The Domain has been the site of free opera events as part of the Sydney Festival since 1982.
The gardens and domain have suffered under the influence of modernism. In the 1920s the site was dug up using a cut and cover construction method to build the City Loop of the underground railway on the western side of the Domain. In 1956 the City of Sydney took the western side of the Domain and constructed a car park with the loss of 47 rare trees. The influence of the car again played out with the construction of the Cahill Expressway between 1958 and the 1960s and resulted in the loss of the Fig Tree Avenue planted in 1847, and the division of the gardens and the domain areas.
In 1978 the administration of the gardens and Domain were transferred from the Department of Agriculture (from 1908) to the Premier’s Department. In 1980 the state government passed the Royal Botanic Gardens Trust Act to secure the extent of the grounds and administration of Centennial Park administration became autonomous. The Friends of the Botanic Garden were established in 1982.

Development of the gardens and Domain occurred in 1970 and 1971 with the construction of The Pyramid as a tropical glasshouse, two annexes were established in 1988 at Mount Annan (native plantings) and Mount Tomah (cool-climate plantings), and in 2016 in the Upper Garden the new Calyx replaced the demolished Pyramid as the tropical plant centre.
