Halls full of massive skeletons, stuffed animal corpses posed on fake landscapes, butterflies pinned to boards - all natural history museums are gloomy places and this is no exception. The collection was founded as part of the University of Wrocław in 1811 and moved to its own building in 1906. The entire collection was destroyed in World War II, but has been replaced since and now numbers about three million animals and half a million plants. You won't find almost any info in English, but for bio-buffs it's the Latin that matters, right? Four permanent exhibits in total - World of Plants, World of Animals, Insects & Humans, and Skeletal System. Last entry 45 minutes before closing.
