This door is the door of the sågverksmuseum on the island Alnö in Sweden. This building was originally a sågverk (saw mill) and is part of a collection of small buildings called the Alnö Hembygdsgård. In the late 1800s there were around 20 saw mills in operation spread over the island Alnö. Around the saws small communities arose. Workers from different part of the Nordic contries moved into the island. But the working-class homes that were rapidly built left a lot to wish about comfort and sanitary conditions.
