Chojna (; ; "King's Mountain in the New March") is a small town in northwestern Poland in the West Pomeranian Voivodeship. It lies approximately south of Szczecin. As of December 2021, the town has a population of 7,330. Chojna is located near two border crossings (Hohenwutzen and Schwedt) on the Oder River with Germany. It participates in the EU Douzelage town twinning initiative. History High Middle Ages From the 10th-12th centuries an early Pomeranian fortification, probably with a market, developed at the location of present-day Chojna. It became part of the emerging Polish state in the 10th century under its first historic ruler Mieszko I of Poland. Because of its favorable location on trading routes leading to the principalities of Greater Poland and the duchies of Pomerania, the settlement developed quickly. Duke Bogusław I of Pomerania was entombed in the settlement's church after his death in 1187. After 1200 the settlement received Magdeburg town rights from Duke Barnim I the Good. It was referred to as "Konigesberge" for the first time in 1244 and passed to the Bishopric of Brandenburg after Bishop Otto of Brandenburg had acquired part of the New March in 1252. Populated with German knights and colonists, the town's name "Konigesberge" evolved into the German name "Königsberg" ("King's Mountain"), with the epithet in der Neumark (i.e. in the New March) added to distinguish it from namesakes in East Prussia and Bavaria. After in 1267 Bishop Henry I of Brandenburg had ceded the "terra Konigesberge" to the Ascanian Margraves of Brandenburg, the town was granted the right to hold a market as well as regional legal jurisdiction, causing it to become the main town of the New March at that time. Late Middle Ages A parish church existed by 1282, while an Augustinian monastery was founded in 1290. From 1310 to 1329 the town experienced an economic boom linked to the grain trade, and received further market privileges. The town hall was built in 1320. Trade goods were shipped over the Oder and rivers. During the 13th and 14th centuries a defensive wall was built around the town with numerous towers and three city gates (, Barnkowo Gate, and Vierraden Gate — the latter demolished in the 19th century). In 1319 a war broke out over control of the region, and the town came again under control of the Duchy of Pomerania, but fell back to Brandenburg in
