The Research Station in Popielno is a unit belonging to the Institute of Animal Reproduction and Food Research of the Polish Academy of Sciences in Olsztyn since 1 January 2016. The activities carried out at the Research Station are aimed at protecting biodiversity by breeding animals of conservative breeds (Polish horses, Polish red and lowland black and white cattle), as well as education and promotion of an active lifestyle.

A memorable history lesson is visiting the Castle in Ryn - a witness to the turbulent history of Masuria and former East Prussia.
