In the area
On the hundreds of mounds of medieval Fryslân there was often a stins: a habitable stone tower with very thick walls, to defend the inhabitants of the mound in times of armed conflict.
One of these stone houses remains (the Schierstins) and here and there remnants can be identified. Of the first stone houses in the city (city stinzen) there are more, greatly modified over time.
Many stinzen have been demolished, but some have developed: the resident (the 'chieftain') expanded his residence into a complex for which the name 'state' was used. Here too, most of them are no longer there.
There are even more beautiful States and Stinzen throughout Friesland.
