Muzeum Przyrody w Olsztynie

An Art Nouveau villa from the late 19th century, once the manor house of the Nagórki estate, holds natural history collections covering zoology, botany and geology, along with early twentieth-century maps of Prussia. The collection numbers about 18,900 items, including a herbarium of some 460 sheets. The permanent exhibition is devoted to the animals of Warmia and Masuria.
