At the onset of preparations of new permanent exhibitions of the National Museum (NM) in 2011, it was necessary to define their content. Several expert teams composed of NM staff and other institutions took part in this process. Historical topics were embraced in a novel perspective, their comprehensive presentation was so far absent in the NM. Social science expositions in the History exhibition will map the development of society from the Early Middle Ages until the end of the 20th century. The People exhibition will interlink the topics of anthropology, archaeology and classical archaeology. Natural science topics will be elaborated on three levels – nature around us, stories of evolution, and an experimental area (ExperiMus). They will reveal processes affecting the shape and transformations of Earth. The Social and Natural science parts will be linked through the Treasury exhibition. The Pantheon and the Children’s Museum will form completely independent units. The architecture of exhibitions will be the result of public tenders conducted in compliance with the Act on Public Contracts. New expositions of the NM are to be opened in 2019 (Natural science) and 2020 (Social science) on a total area of 12 000 m2.
