Sydney Observatory
Built in the 1850s, Sydney's copper-domed, Italianate sandstone observatory squats atop pretty Observatory Hill, overlooking the harbour. Inside is a collection of vintage apparatus, including Australia's oldest working telescope (1874), as well as background on Australian astronomy and transits of Venus. Also on offer are entertaining tours (adult/child $10/8), which include a planetarium show. Bookings are essential for night-time stargazing sessions (adult/child $22/17), which run Monday to Saturday, and Aboriginal sky storytelling sessions (adult/child $18/12). All tours are great for kids.
