The Open Air Museum of Lithuania in Rumšiškės (Kaišiadorys District) is an exposition in the open air. The core exhibits of this museum include dwelling houses, farmstead buildings and folk art monuments transferred from all ethnographic regions of Lithuania, Aukštaitija, Žemaitija, Suvalkija and Dzūkija, and reassembled in a 175-ha area, in a beautiful location near the Kaunas Man-made Sea and Praviena rivulet. Some of the buildings were constructed 200 years ago and earlier. They acquaint visitors with the mode of life as well as housing construction and equipment techniques of people during various periods. 140 buildings are exposed as farmsteads and villages while town’s buildings are grouped around a square.
