Welcome to naturum

Exhibitions, tours and shop

Come and see the Baltic Sea exhibition – to understand how the Baltic Sea ecosystem functions and how life once was in the archipelago. Peek at plants and animals in the aquarium, fast-forward the land uplift, and much more.

Go on tours with our nature guides or try scoop-netting on the meadow and in the sea. We also offer guided tours especially for schools or other groups.

There is a small shop in naturum, where you can buy books about animals and plants, as well as butter fly nets and other things useful in nature.

You can participate in different activities during the summer season. Foto: Anne-Christine Troberg, Bengt Håkanssson, Helena Herngren.
