Gripsholm Castle
The royal family continued to use Gripsholm Castle during the 17th-century. It was the dower residence of the widow of Gustavus Adolphus of Sweden, Maria Eleonora of Brandenburg, who lived here from 1636 until 1640. Between 1654 and 1715, Gripsholm Castle was a part of the dower granted to queen Hedvig Eleonora, who often lived there with her court even before being widowed in 1660, and who rebuilt and expanded it in several ways. After her death, however, the Castle was abandoned by the court for some time. For a period during the 18th-century, it was used as a prison.
