Struensee at the Citadel

Today, the buildings inside the Citadel are used as military barracks and offices. However, the area is open to the public and a favourite green lung for a brisk walk or jog on the ramparts.


Johan Friedrich Struensee was arrested on the night of 17 January 1772 after a masquerade ball at the Court Theatre in Copenhagen.

He was placed under arrest at the Citadel where he stayed until his trial on 21 February. He was convicted of lese-majesty because of his affair with Queen Caroline Mathilde.
