The north of the city was defended by two nearly identical round towers positioned on either side of a water defence, the Upper Pond or Oberteich as it was known in German, with the west one named the Wrangelturm (Wrangel Tower).  It, like its sister tower the Dohna, was named after a living (at the time of construction at least) Prussian Field-Marshall.  The Wrangel took its name from Friedrich Graf von Wrangel (1784 –1877) who became a Field-Marshall of the Prussian Army in the year of the tower’s completion – 1856. Von Wrangel didn’t just have a successful career in the military, but he was descended from one of the best known Baltic German noble families, a family whose connection with Königsberg can be traced back to the 16th century.

The tower is 12 metres in height, 34 metres in diameter and has walls which are over 1.5 metres think in places. In years past the tower was open to the public and had a restaurant, a roof terrace and some small souvenir shops. These days it is closed off from the public and unlike many of the other fortifications, looks rundown and old giving you a different perspective than the recently cleaned and modernised defences.
