Being the first and the richest natural history museum on the Balkans, the National Museum of Natural History in Sofia (NMNHS) studies, preserves and disseminates information about the living and non-living nature both in Bulgaria and throughout the world.NMNHS is the only national institution directly engaged with the preservation of scientific collections of live and non-live nature from Bulgaria and the world. The study of biodiversity, environmental protection and the evolution of organisms are the museum’s major priorities. Consequently, the main task of NMNHS is the all-around study of the fauna, flora, fossils, minerals and rocks of Bulgaria and other countries. It develops the following scientific areas: taxonomy, faunistics, zoogeography and ecology of arachnids, myriapods, insects and all classes of vertebrates; taxonomy of fossil mammals, birds and brachiopods; floristics; mineralogy.
