Kostrzyn nad Odrą, Border town in western Poland
Kostrzyn nad Odrą is a town in western Poland where the Warta River flows into the Oder River, forming a natural frontier with Germany. This location at the meeting of two major waterways has made the settlement a key crossing and trading post for centuries.
A written record first mentions the settlement in 1201, and it later came under Templar control. The medieval center was completely destroyed during World War II and never rebuilt afterward.
The city underwent a significant demographic transformation after 1945 when German residents left and Polish refugees from Soviet-annexed territories established new communities.
A public park now displays the foundations and cellars of former buildings, with signs marking earlier street names and locations. The site is freely accessible and can be explored on foot.
The 17th-century fortress grounds now lie within the Warta Mouth Landscape Park, where traces of old fortifications appear among reedbeds and wetland meadows. The water channels and moats from the earlier defense lines remain partly visible today.
