Visitors exploring the original laboratory where Nikolai Miklouho-Maclay conducted his research during the former Marine Biological Station's 2025 Open Day.

Located at Camp Cove, the Former Marine Biological Station was one of the first buildings established in Watsons Bay. This pleasant but unassuming sandstone cottage is included on the Commonwealth Heritage List, due to its layers of historical significance, and has the distinction of being the first research facility of its kind in the Southern Hemisphere.
