Sydney Observatory building on Observatory Hill with its time ball

Sydney Observatory

ArchitectureHistoryScienceOpens 12pmFreeWynyard

Perched on Observatory Hill above The Rocks, this heritage-listed 1858 building began as a time-ball and weather station and is now a working astronomical observatory run by the Powerhouse. By day the free grounds and ground-floor galleries explore First Nations astronomy and the site's history; after dark, ticketed tours put visitors behind a 19th-century refractor and a modern telescope for views of the night sky over Sydney Harbour.
