The Natural History Museum is Norway's largest collection of natural science objects. 6.2 million objects are found here, representing 65% of the country's total natural history collections. Some of these collections are available to the public in the Botanical Gardens and the museums there. In addition to the research conducted at the museums, updating and maintaining these collections is an important part of NHM's tasks. Collett's House (Zoological Museum) has permanent and changing exhibitions for the public. The entrance is through a modern pavilion, marked Museum entrance, where you will also find the museum shop. Brøger's House (Geological Museum) is currently closed to the public, but you will find many of the highlights of our objects in the exhibitions at Collett's House. Lids House (Botanical Museum) contains offices, herbaria, archives, etc. This is used by researchers and is not open to the public. The botanical garden covers 150 acres and has about 35,000 plants spread across approximately 7,500 species.
