Rygiškių Jono gymnasium museum was established in 1967, in commemoration of the 100th anniversary of the old gymnasium.
The idea of establishing a museum in this gymnasium was fostered during the interwar period: folklore, ethnographic materials were collected, but everything that was collected during the Second World War was lost or destroyed. Lithuanian language teacher Jonas Kvederaitis began to foster the idea of creating a museum during the interwar period. In 1965 his work was taken over by teacher Vincas Peckus: exhibits were collected, and an exposition was prepared. Before there was a museum, the premises served as an auditorium in the 19th century, after that it became an orthodox chapel. At the present day, the museum has approximately 7,000 exhibits.
The current head of the museum is Judita Zubavičienė
