Fortress Malmo - this castle, situated in the city of Malmo Skåne in southern Sweden. The first building of the fortress was built in 1434 by King Eric of Pomerania in order to strengthen the protection of the city against a possible threat from the sea. This castle was demolished in the early 16th century, and a new one was built in its place in 1530 by the Danish King Christian III. Historically, the fortress of Malmö was one of the most important strongholds of Denmark.

Within five years (from 1568 to 1573) the castle was the place of detention of James Hepburn, 4th Earl Bothwell, the third husband of Mary Queen of Scots. Earl was taken into custody by order of the Danish King Frederick II, when his ship ran aground during a storm in Bergen, Norway. He was sent to imprisonment in a fortress Malmo despite the fact that earlier he was released from the Tower for lack of evidence in the murder of Mary's second husband, Henry Stuart, Lord Darnley. This act historians explain that being unmarried Frederick II took care of Queen Elizabeth I, and was even made a knight of the Garter. However, some sources point to the second reason for his involvement in this matter, he is believed to have hoped to get from Scotland ransom for the prisoner.

In 1828, the fortress of Malmö finally loses its importance as a military fort and becomes a prison. Later, the building of the fortress was used as an emergency shelter. In fact, building the castle it was restored in 1928, and today it gives us an idea of ​​how it looked in 1500-1600-ies. In 1937 there was founded a museum. Three prison barracks have since been demolished and replaced the existing museum building.
