The stone fortress Carlsten was built in Marstrand by order of King Charles X Gustav, whose name it was named after. It performed defensive functions until 1882, but it served military purposes until the 1990s. Currently, it houses a historical museum. The fortress can be visited alone or in the company of a guide. The visit usually takes about an hour.
The fortress was built under the Treaty of Roskilde, concluded in 1658 between the kings of Denmark and Sweden. Initially, it was a prison, and only prisoners worked on the construction site. By work, the inmates earned their food - if they were unable to work, they did not receive food.
Over time, the fortress was transformed into military barracks. In the 19th century, they were inhabited by about 600 soldiers. During the tour, it is worth seeing the renovated barracks and the Commandant's House from 1775. The latter housed not only the fortress commander's apartment, but also cells for prisoners of noble origin.
