Both the older, Gothic portion and the newer, neo-classical building for the government offices form a Rijksmonument complex.
The older portion is in use as the local museum of Kampen.
Precise dates for the old part of the building are not available, but various decorations can be dated, most notably the fireplace in the sheriffs’ courtroom, which was made between 1543 and 1554 by the sculptor Jacob de Nole.
[1] By the 19th century, the city hall had become cramped and a new neo-classical addition was built on the end.
For this the old renaissance gate needed to be deconstructed and the painter Cornelis Springer captured it in a nostalgic painting in 1832: Media related to Raadhuis (Kampen) at Wikimedia Commons
