The well preserved, 17th century Elfsborg Fortress is located on a small island at the entrance of the harbour, at the mouth of the Göta River near Gothenburg. With a fascinating history of battles against the Danes, the fortress was once the mightiest citadel in Sweden for coastal defence and is highly popular with visitors. Boat tours of the archipelago offer passage to the fort, along with sights of the pretty waterways of the river. A dramatised tour is included in the admission fee.
