I visited Roros on a day trip by train from Trondheim. The train journey involved a steep climb, with a substantial drop in temperature, even in August.

The town was compact enough to visit all the significant features like the smelting area, slag heaps and workers' cottages on foot, interspersed with visits to the several hot soup kitchens available.

The construction of the houses was of great interest to me, with the walls made from rough hewn logs with interlocking joints at the corners and grass growing in a layer of topsoil on top of the shingle roofs.
