Sassenpoort

The Sassenpoort is a gatehouse in the city wall of Zwolle, the Netherlands. It was built in 1409 out of dimension stone, mostly trachyte and tuff, and restoration work was done in 1893-1898. The gatehouse is a rijksmonument and is part of the Top 100 Dutch heritage sites.
The city of Zwolle experienced its heyday during the 15th century. It became a member of the Hanseatic League in 1407, and the city gates represent the wealth of this period. In 1893 the city government of Zwolle gave the Sassenpoort to the Dutch national government, as a location to store the national archives, a function the building no longer serves. The building remains to this day property of the national government.
