Hemmed in between the traffic roundabouts of Slussen and the steep hill up to Mosebacke Torg is Stockholm City Museum. It is housed in a late seventeenth century building originally designed by Tessin the Elder as Southern City Hall. After a fire, it was completed by Tessin the Younger in 1685. it has been used for various purposes over the centuries, including law courts and dungeons, schools and city hall cellars, theatres and churches, until in the 1930s it became the city museum.

The museum documents the history of Stockholm. The city’s main stages of development are described in a slideshow and a series of four permanent exhibitions. The first starts with the Stockholm Bloodbath of 1520 and continues through the seventeenth century. The eventful eighteenth century is illustrated with exhibits that include the Lohe Treasure. The other sections depict industrialization in the nineteenth century and the tremendous growth in the 20th century with the emergence of a new city centre and new suburbs.
