A stairway leads from the foyer up to the octagonal lookout tower whose round glass section resembles a lighthouse. At the top, it is possible to step outside and view the landscape from above. From here is possible to enjoy the view of Christiansø, Gudhjem, Allinge and beyond to Sweden. More information about Bornholm’s granite is found in a small permanent exhibition set up in the lookout tower by the Danish Society for Nature Conservation.
Like the tower, the bridge is also reminiscent of a ship. It is constructed like a ship’s bridge in steel and teak and ends in a canvas-covered lookout pavilion. The bridge protrudes from the actual museum and extends the body of the building towards the coast. The tall columns supporting the bridge make you feel like you are stepping into the landscape at treetop height.
Pure natural materials – such as tile, zinc, brick, granite, sandstone and wood – have been used throughout the museum. The Street is paved with Bornholm granite, while sandstone is used in the smaller rooms. All the floors of the exhibition rooms are wooden. In the special exhibition rooms, the wood is laid as end-grained blocks, also serving as a climatic buffer.
