A glimpse of the entire city can be enjoyed from the ruins of Gustav Fort: from here you can see the harbour and the few remaining Swedish buildings, recognizable by their guillotine windows.Built in 1787 by the Swedes as one of three forts to protect the harbour, this site now has the remains of a vaguely bottle-shaped lighthouse along with the vestiges of a stone guardhouse, cisterns and four cannons, two of which are on loan from the Swedish Maritime Museum.
