In 1311 Novgorodian troops attacked "the castle of Vanai", but were unable to conquer it. In early 14th century the military role of Hameenlinna castle diminished. In 1496, however, a Russian military campaign extended as far as the environs of the castle. The castle passed to King Gustavus Vasa from Danish troops in 1523 without a battle.
During the 1560s and '70s it was reinforced with the addition of two rondells. King Gustavus II. Adolphus visited the castle in 1614 and in 1639 the settlement next to the castle was given a town charter. Hameenlinna castle became Finland's largest military depot in the 18th century and a prison in 1836. Restoration works began in 1953. (Kari Uotila)
