The magnificent Botanisk Have belonging to the university look over the old town. The exterior section includes numerous varieties of plants (arboretum, and medicinal, venomous and aromatic plants). In the middle of the garden, greenhouses extending over 2 000m² house more than 5 000 species of tropical and subtropical plants. A series of adjoining rooms takes you through vegetation which becomes progressively denser. Ultimately you come out into a room with a tropical climate, in which parrots perch within a forest of gigantic plants.
