Pokrzywno

Pokrzywno is a small village located in north-central Poland within the Kuyavian-Pomeranian Voivodeship, specifically in Grudziądz County and the administrative district of Gmina Gruta. While the settlement itself dates back to at least 1222, when it was documented under the Latinized name Copriven, its historical prominence stems from a significant castle constructed on the site in 1242. Built by the Teutonic Order atop an older fortification, the structure served as the seat of a commandery for nearly 140 years, functioning as a key administrative and military hub for the Order between 1278 and 1416.

The castle witnessed a turbulent history marked by frequent changes in ownership and repeated destruction. During the Polish-Lithuanian-Teutonic War in 1410, Polish forces captured the stronghold, after which King Władysław II Jagiełło granted it to Dobiesław of Oleśnica. Following further conflicts, including the Swedish invasion during the Deluge in 1657, the complex suffered severe damage. The castle chapel endured fires in 1611 and later destruction by Swedish troops, undergoing renovations each time before finally collapsing in 1789. After falling into semi-ruin, the remaining stone structures were systematically dismantled and used as a quarry to supply building materials for local houses and roads.

Today, Pokrzywno remains a quiet village with a population of approximately 300 residents. Although the once-mighty fortress no longer stands intact, visible ruins of the castle still exist within the village limits, serving as a tangible reminder of its medieval origins and strategic importance. These remnants offer a glimpse into the region's complex past involving the Teutonic Order, Polish royalty, and various invading armies, making the site a point of interest for those exploring the historical landscape of northern Poland.
