Established in 1818, it has surprisingly managed to keep its location unchanged – it still is seated in the Academia Petrina. Nowadays, the museum hosts permanent exhibitions of the famous artist Ģederts Eliass and tells the history of Jelgava, Zemgale (Semigallia) and of the museum premises. To reflect the region’s prehistoric and Livonian period, it exhibits archaeological findings of Stone Age settlements in Semigallia, items of ancient Semigallian burial sites and hillforts. An exhibition by means of photographs depicts ancient Semigallian hillforts located in Dobele, Dobe, Mežotne and Tērvete. In order to inspire the imagination of visitors regarding the magnificence of ancient Semigallian hillforts and castles, a model of Tērvete hillfort is exhibited in the museum. Besides, there are two unique virtual expositions available — “Wars and warriors in Jelgava over centuries” and “Zemgale folk costume and its’ wearing traditions”.
