Read moreThe province of Bohuslän became Swedish following the Roskilde Peace Treaty in 1658. Realising the strategic value of the port of Marstrand, King Charles X ordered the construction of fortifications and so the construction of the fortress began. It took about 200 years to complete. The fortress was built by convicts over the years. The most famous of these prisoners was Lasse-Maja - a kind of Swedish Robin Hood - who managed to escape from the fortress by disguising himself as a woman.
