Sydney Observatory

Sydney Observatory, (1858) occupies a heritage-listed sandstone building in The Rocks on Observatory Hill. It boasts panoramic views of Sydney Harbour. The Observatory is set amongst a beautiful garden which recreate the original layout and vegetation of formal 1880's gardens.

2018 is the 160th anniversary of the Observatory. It’s one of the most significant sites in Australia’s scientific history. It has a central role in the history of timekeeping, meteorology and astronomy.

Beginning with exhibitions on Indigenous astronomy, then telescope domes and opportunities to explore the sky with guides. Tours provide access to an 29cm lens telescope from 1874, a 42cm computer-controlled telescope and hydrogen-alpha solar telescope.

At night, explore the Southern night sky – including stars only visible in the Southern Hemisphere. Stars, planets in the solar system, Moon or nebulae - light years away can be observed during night tours. Day tours observe the Sun with special lenses.

Explore the Universe in the 3-D Space Theatre or Sydney Planetarium for a tour of the Southern Sky. Watch films about astronomy, history of space flight and more.

The Observatory is free to walk around the grounds, fort remains and exhibitions.

Bookings essential for night or day telescope tours.
