The site of Marstrand was chosen because of its location and its access to an ice free port. Initially a square stone tower was constructed, but by 1680 it was reconstructed and replaced by a round shaped tower. Successive additions to the fortress were carried out, by the inmates sentenced to hard labour, until 1860 when it was reported finished. The fortress was decomissioned as a permanent defense installation in 1882, but remained in military use until the early 1990s.
The fortress was attacked and sieged twice falling into enemy hands. In 1677 it was conquered by Gyldenlöwe, the Danish military commander in Norway and in 1719 by the Norwegian Admiral Tordenskjold. At both occasions the fortress was returned to Swedish control through negotiations and treaties.

Morgan testified she became aware Carlsten was a Scientologist "from some of the things in the office," including a poster of "the Bridge to Total Freedom," Scientology's reference to its study process.
Carlsten's attorney, Lanni, argued that Scientology was being used by Morgan as a smoke screen.
