Chojna pronounced [ˈxɔi̯na] (German: Königsberg in der Neumark; Kashubian: Czińsbarg; Latin: Regiomontanus Neomarchicus "King's Mountain in the New March") is a small town in northwestern Poland in the West Pomeranian Voivodeship.

Because of its favorable location on trading routes leading to the principalities of Greater Poland and the duchies of Pomerania, the settlement developed quickly.

From 1310 to 1329 the town experienced an economic boom linked to the grain trade, and received further market privileges.

The Church of St. Mary and the new town hall (1410) built during this time were some of the most aesthetically pleasing Gothic buildings in the New March.

The town began to revive economically after the foundation of the Kingdom of Prussia, becoming the seat of the government (Kriegs- und Domainenkammer) of the New March in 1759 during the Seven Years' War.

In 1767 the city gates towards Schwedt and Bernikow were partially dismantled to provide stone for the construction of a military barracks at the former monastery.

[4] The place became the county seat of the Königsberg district [de] in 1809 and part of the Frankfurt Region in the Prussian Province of Brandenburg in 1816.

On 4 February 1945 Kurt Flöter, Königsberg's then mayor, was condemned to death by hanging by an SS court martial chaired by Otto Skorzeny, because he had fled before issuing a general evacuation order by the military.

The entire city centre with the Church of St. Mary and the town hall was burned to the ground by the Soviets on 16 February 1945.

After the German capitulation, under border changes promulgated at the Potsdam Conference, the town became again part of Poland; the local population was dispossessed and expelled.

Chojna's two main landmarks are thus the town hall [pl] and the Church of St. Mary, both historical buildings by the Gothic architect Hinrich Brunsberg.

This active town twinning began in 1991 and there are regular events, such as a produce market from each of the other countries and festivals.

[2][13] Discussions regarding membership are also in hand with three further towns (Agros in Cyprus, Škofja Loka in Slovenia, and Tryavna in Bulgaria).
