The fortress is a fortification located on Oxdjupet, the approach to Stockholm. The fortress consists of a tower, a beach fortification, and courtyards. The complex was part of the defenses built along the Swedish east coast after the Russian devastation of 1719 to protect Stockholm. The fortress was completed in 1735. At that time, it was one of the strongest fortresses in Europe. Source: Wikipedia
