Opaleniec

Opaleniec [ɔpaˈlɛɲɛt͡s] (German: Opalenietz, 1938-45: Flammberg) is a village in the administrative district of Gmina Chorzele, within Przasnysz County, Masovian Voivodeship, in east-central Poland. It lies approximately 4 kilometres (2 mi) north of Chorzele, 30 km (19 mi) north of Przasnysz, and 119 km (74 mi) north of Warsaw.

Before 1945 the area was part of Germany (East Prussia). In the East Prussian plebiscite of 1920, which was largely boycotted by ethnic Poles, the inhabitants voted to remain in Germany. After World War II the region was placed under Polish administration by the Potsdam Agreement under territorial changes demanded by the Soviet Union. Most Germans fled or were expelled and replaced with Poles expelled from the Polish areas annexed by the Soviet Union or forced to settle in the area through Operation Vistula in 1947.
