The Earth Museum continues the tradition of the Earth Museum Society established in Warsaw on a social initiative in 1932. In 1959 the institution was incorporated into the Polish Academy of Sciences. Our collection has over 90,000 inventory numbers. Research work – of interdisciplinary character – carried out in the Museum of the Earth is strictly connected with the scientific elaboration of geological collections i.e. rocks and minerals (including meteorites), paleozoological and paleobotanical fossils, amber as well as other fossil resins and documents from the history of geological sciences.
