Wiśniowo Ełckie

Wiśniowo Ełckie is a village in the administrative district of Gmina Prostki, within Ełk County, Warmian-Masurian Voivodeship, in northern Poland. It lies approximately 9 km north-east of Prostki, 14 km south-east of Ełk, and 134 km east of the regional capital Olsztyn. It is located in the historic region of Masuria.

History
The origins of the village date back to 1486, when Gotard Korbowski was granted 66 włókas of land to establish a village. As of 1600, the population was solely Polish.

Under Nazi Germany, the village was renamed Kölmersdorf to erase traces of Polish origin, and was the location of two labour camps of the Reich Labour Service. Following World War II, in 1945, the village became again part of Poland, and its historic Polish name was restored with the addition of the adjective Ełckie after the nearby county seat of Ełk to distinguish it from other villages of the same name.
