Home to the Kaliningrad Amber Museum the tower is named after Prussian Field Marshall Friedrich Emil Graf zu Dohna-Schlobitten who, among other things, was decorated in the war against Napoleonic France while serving in the Russian army. On his retirement in 1854, he was made a Field Marshall and the tower named in his honour was completed a year before his death in 1859. The Dohna Tower sits across the water from Wrangel Tower and with canon mounted in between behind the defensive wall (part of which is still visible) you can imagine how the fortified Königsberg would have looked if you stand at the Upper Pond. In the Battle for Königsberg, the soldiers in the Dohna Tower refused to surrender until the Act of Capitulation had been signed and was the last place in Königsberg to hold out, not giving out until April 10th when a Red flag was raised over the tower. It’s worth a visit as it is possible to walk around and inside the tower to get a better idea of the construction that is impossible to do with the fenced-off Wrangel Tower. While you are there also take time to pop into to the Amber Museum which, even though it’s been completely re-modelled, does give you a view of the three floors and the inner courtyard.
