On the island of Djurgården in Stockholm lies the worlds oldest open-air museum, founded in 1891. It shows typical houses, dwellings, churches etc. from over five centuries, including museum employees in period correct clothing inside.
It’s a kind of a time travel, and all the people inside the houses really live up their figures, be it in a farm from 1700 or a house from the 1930ies. Everybody is really friendly and provides you with a lot of informations on the time and the houses.
Skansen is definitely one of the places to visit in Stockholm – but be aware it is huge. We spent a day there and only saw about one third of the area.
