Founded in 1739, the National Museum of Natural History is the largest museum complex in Sweden. More than nine million biological and mineral samples are stored in this monolithic brick building designed in 1907 by Axel Anderberg, architect of the Royal Opera. Beneath the black-shingled roof and light-filled cupola stands an exceptionally well-made tableaux of extinct creatures, prehistoric man and Swedish wildlife. Visitors enter the dinosaur exhibit through a dark volcanic room to find sharp-toothed birds sitting in trees above a skeletal T-Rex. The hands-on exhibits about space and the human body include a red Martian landscape, a spaceship's cockpit and a walk-through mouth. Many exhibits are labelled in Swedish only, so borrow a booklet in English from the information desk.
Sweden's only IMAX cinema, the Cosmonova, shows movies about the natural world on its huge screen - which also functions as a planetarium. Under-5s are not admitted. The gift shop sells science books, plastic animals and polished rocks.
