This military post was developed in 1885 as part of Dunedin’s harbour defences. It is now open to the public and features a lighthouse, tunnels and a working Armstrong disappearing gun. The fort is also home to seals, a Stewart Island shag colony and the world’s only mainland albatross colony.
The Royal Albatross Centre has displays that provide insight into these enormous sea birds, which have a wingspan of 3m, and it also leads guided tours of the albatross colony between late November and mid-September.
