The famous Low German poet Fritz Reuter spent part of his time in Dömitz - as an inmate of the fortress. Today, there is a memorial in his honor on the fortress grounds.
Fritz Reuter served the last of seven years as a prisoner in Dömitz Fortress between 1838 and 1840. There he is said to have had an exuberant love affair with the daughter of the lord of the castle. In the 1862 story "Ut mine Festungstid," Reuter recounts the experiences of his imprisonment. In 1958, a memorial to the Low German poet was established at Dömitz Fortress. A permanent exhibition with picture and written panels provides information about Reuter's student days in Jena, his activities in the fraternity and the trial for high treason, as well as his subsequent imprisonment. Also on display is a comprehensive collection of Reuter emergency money from the 1920s.
