Steenwijk is the second largest town in Northwest Overijssel, after Kampen (also known as the Kop van Overijssel). An old fortified city with canals and ramparts dating back to the Eighty Years' War.
Steenwijk is located in the head of Overijssel on the border of several moraines (the Woldberg and the Havelterberg) and the low moor area of Giethoorn, De Wieden and De Weerribben. Originally a small river flows through Steenwijk, the Steenwijker Aa, which was created by melt water. Later this Steenwijker Aa was canalised and was then called from Steenwijk het Steenwijker Diep and this made the city accessible for shipping. There is a small marina at Steenwijker Diep. The cityscape is determined by the Sint Clemenstoren, with its height of 87 meters the fourteenth highest church tower in the Netherlands. wiki
The name is related to the many erratic stones in the ground in the area.
