Objects found during the excavations show that the inhabitants of Södermalmstorgs were quite wealthy, as early as the middle of the 1300s. Among other things, you have found beautiful drinking glasses made in Venice and ceramics from Persia.

Disproves previous theories

Also found in the plots were brick houses where the roofs were covered with bricks and the windows had stained-glass windows, which is unparalleled in 13th-century Stockholm and which disproves previous theories of the city's growth.

"It is a huge find that writes about the history of medieval Stockholm," says Kennet Svensson, chief archaeologist at Archeology Consultant.

A total of 1,200 square meters are searched

A total of 300 square meters have been excavated between 2013 and 2015. An unusually large area in the middle of a big city. It shows that Södermalm was Stockholm's and Sweden's very first suburb where wealthy German merchants from Hansan probably lived in a developed urban environment.

- This shows that Stockholm has been larger and urbanization is much more complicated with medieval urban development, says Kennet Svensson.

So the most important finds have now been released in a 460 page thick book. In the next era of the sluice project, a 900 square meter area will be excavated west of Södermalmstorg.
