Burg Grimnitz is a castle ruin located in the Joachimsthal district of Brandenburg, Germany. Originally a Höhenburg, it was built on a sandy elevation and served as a Romanesque border fortress for the Ascanian margraves, strategically positioned to secure the road between Werbellinsee and Grimnitzsee towards Uckermark and Pomerania. The first documented mention of the castle dates back to 1297, although it is believed to have been established earlier under the rule of Margraves Johann I and Otto III of Brandenburg, who used it as a hunting lodge near the Schorfheide forest. The castle fell into disrepair after 1340 but was restored in 1514 by Elector Joachim I and modernized by architect Caspar Theiss. In 1529, the Treaty of Grimnitz was signed here, marking an important historical event. The castle suffered significant damage during the Thirty Years' War and was largely abandoned by the 18th century. In 1860, it was sold for demolition, but in 1885, the ruins were gifted to German Emperor Wilhelm I. Today, the site is owned by the Grimnitzer Glashüttenverein, reflecting its historical connection to the Grimnitzer Glashütte, a glassworks established in the area during the late 16th century.
