The city is built on hills surrounding one of the world's largest natural harbours, which is commonly known as Sydney Harbour, where the iconic Sydney Opera House and the Harbour Bridge are prominent structures. The hinterland of the metropolitan area is surrounded by national parks, and the coastal regions feature many bays, rivers, inlets and beaches, including the famous Bondi and Manly beaches.
