The 11-story red brick building is characterized by an octagonal profile. Visitors can take on the 50-meter way to the top with an observation deck. It has a good view of the ruins of the former Teutonic castle, the city, and the area.
The tower is the sole remnant of the 14th-century medieval castle in which the construction of the Teutonic stronghold started. It survived thanks to Frederick William IV of Prussia who, in 1842, contributed to the suspension of demolition and devastation of former Teutonic headquarters.
Despite their origin, the tower and the castle for years belonged to Polish Princess Anna Wazówna. It was then when the tower was rebuilt changing its pointed top to the present and adding the flag, serving as a weather vane, with coats of arms of the Vasa Dynasty, Gotland, Sweden, initials AP, and the date "1616". The initials refer to Anna Princes meaning Princess Anna.
There is a legend about commander Baldwin Stal whose ghost wanders the tower and cannot find peace.
