Wirwilty
Wirwilty is a village in the administrative district of Gmina Bartoszyce, within Bartoszyce County, Warmian-Masurian Voivodeship, in northern Poland, close to the border with the Kaliningrad Oblast of Russia. It lies approximately north-east of Bartoszyce and north-east of the regional capital Olsztyn.
Before 1945 the area was part of Germany ( East Prussia). After World War II the region was placed under Polish administration and ethnically cleansed according to the post-war Potsdam Agreement. The native German populace was expelled and replaced with Poles.
