The Natural History Museum at the University of Oslo, located in the heart of the Botanical Gardens of Tøyen, is the oldest and largest natural history museum in Norway, with over 2 million specimens including fossils, minerals, rocks, plants, and taxidermied animals. Its roots date back to 1814, but the collection was consolidated in the zoological, botanical, and geological museums and unified in 1999, taking on its current name in 2005.

Journey through evolutionary life with the Evolution of Life hall, from the Cambrian period to mammals: it houses the famous fossil Ida (47 million years old), one of the most complete primates in the world, and a life-size replica of a Tyrannosaurus rex. The geological section, spanning four floors, showcases spectacular Norwegian crystals, meteorites, gems, and the captivating Crystal Cave in the basement, with interactive installations and multimedia insights on geological time.

The Zoological Museum, with realistic dioramas and habitats (polar bear, okapi, penguins, Arctic fauna), attracts both families and those curious about global fauna.
