1. The Sydney Tower has been an integral feature of the Sydney skyline for over 30 years. Measuring 309 metres at its highest point, it is one of the tallest structures in the southern hemisphere and by far the tallest building in Sydney.
2. After almost 40 years standing over the water, the Sydney Harbour control tower may be demolished.
The 82m tower at the northern end of Barangaroo has been gathering dust since Sydney Ports relocated its harbour control operations to Port Botany in May.
The Barangaroo Development Authority wants to buy the Sydney Ports tower, which is on land earmarked as a headland park as part of the Barangaroo redevelopment.
