The Best Sight in The Rocks, Sydney

Originally a signaling station for communicating with ships anchored in the harbor, this handsome building on top of Observatory Hill is now an astronomy museum. During evening observatory shows you can tour the building, watch videos, and get a close-up view of the universe through a 16-inch mirror telescope. The digital Sydney Planetarium showcases the virtual night sky to just 20 visitors at a time in a small theater. Reservations are required for the evening shows only.
