About the building
Sydney Observatory stands on Gadigal land at the highest point of Warrane overlooking Sydney Harbour. The site is a place of scientific and cultural significance in Australia’s pre- and postcolonial history.
From 1797, the site was used for Sydney’s first windmill, before being identified as the location for Fort Phillip in 1804. From 1808, it served as a signal station, with its flagstaff helping connect the colony’s network of communications. The observatory was built in 1858 to provide a timekeeping service to the colony, which later led to meteorological, surveying and astronomy activity. The site incorporates buildings designed by Colonial Architects Mortimer William Lewis, Alexander Dawson and James Barnet. Largest among them is the Italianate-style sandstone observatory building, complete with time-ball tower, telescope domes, offices and family accommodation.
The site has a rich history as the workplace and family residences of government staff including signal masters, messengers and astronomers. By the late 20th century, the observatory’s scientific activities had reduced to a point where it was transferred to the Powerhouse to manage as a museum and education facility.
Sydney Open visitors will be able to tour the observatory building to explore objects from the Powerhouse Collection and examine the site’s role in timekeeping, surveying and astronomy. After climbing up the narrow staircases to the observatory’s domes, visitors can see the historic and modern telescopes and take in spectacular views across Sydney Harbour.
