The Prussia Columns are two monuments, over 15 metres high, that were erected in the years 1854 and 1855 by order of the Prussian king, Frederick William IV on the southeast coast of the German island of Rügen near Neukamp and Groß Stresow. Both villages are today part of the municipality of Putbus.
The monument near Neukamp was inaugurated on 15 October 1854 and the one near Groß Stresow exactly one year later, on the 60th birthday of Frederick William IV. The drums and parts of the pedestal were carved from one of the largest glacial erratics on and around Rügen, the Great Rock near Nardevitz on Rügen's Jasmund peninsula. Most of the rock was destroyed as a result of being quarried for the columns. Nevertheless, it is still impressive today, and sticks 3 metres out of the ground.
