Designed by prominent colonial architect John Kirkpatrick, the former Marine Biological Station at Camp Cover, Watsons Bay, is recognised as the first biological research station in the Southern Hemisphere.
Built in 1881 as a place for Russian scientist Nikolai Nikoleavich de Miklouho-Maclay to study local marine life, this beautiful sandstone cottage was later acquired by the Australian Army to house officers. It received the prestigious Commonwealth Heritage listing in 2004 and is one of the most historically significant buildings on the Sydney Harbour foreshore.
