The NTNU University Museum has three main buildings at Kalvskinnet in the centre of Trondheim, as well as workshops and storages.

The three buildings are named after the three founders of the Royal Norwegian Society of Science and Letters: Gunnerus, Schøning and Suhm.

The Gunnerus Building

The Gunnerus Building was drawn by several architects, including E.C.B. Christie, and built in 1868 in a simple New Roman style with evenly grouped, narrow round arch windows.

In the protruding centre part (facing Erling Skakkes street) we find the earlier entrance, framed by steatite pillars. The current entrance faces the museum area from Gunnerus street.

The building took place in stages over a longer period, a fact which is reflected by the different shades of colour on the façade.

The Schøning Building

The Schøning Building consists of several buildings that used to be production facilities for the brewery E.C. Dahl. The museum bought the buildings after the brewery moved to a different location, and in the 1970s, they were converted into offices for the museum staff, laboratories and stores.

In 2005, parts of the building were upgraded and taken in use by the museum's administration.
