The museum itself, all expositions are dedicated to the underground Komsomol organization "Young Avengers". Documentary photographs, various official papers and personal belongings of Komsomol members (among the famous ones are the heroes of the Soviet Union, Zenkova E.S. and Portnova Z.M.). The museum is small, there are only four permanent exhibitions, imported exhibitions on the second floor (when we were there there were none). The guide, Yuri, conducted the tour very fascinatingly, interested a two-year-old kid and a teenage girl, and the adults were also interested. The museum building is located in a picturesque location on the banks of the Obol River, on the territory of the former Grebnitsky estate and park complex.
