The history of museum is closely associated with Mieczysław Ratasiewicz. In 1962, this young man got his first job at school in Gołdap. Over the years, he was passionately collecting and documenting all changes and discoveries in the region. One day, the collection has become really valuable and it was decided to create a special section in museum for it. The most interesting exhibits include war memorable, historical, ethnographic and geological objects.
First Jews arrived to Gołdap in thirteenth century. Their life in here was not easy, due to the pressure from liberal policy of Prussian rulers. The extermination of Jews from Gołdap began in the second half of 1930. They burnt and demolished their synagogue, many of them were killed. On Jewish cemetery there are about twenty graves, the oldest comes from 1860.
