In 1629's-Hertogenbosch was conquered by Frederik Hendrik in a legendary siege.'s-Hertogenbosch flooded the surrounding countryside so that the city could not be conquered. She was called the Swamp Dragon. FH succeeded anyway by building 45 kilometers of dikes around the city. That's what this cycle route is about. Then he dammed the rivers and began to drain the area with windmills and steed mills. He built an inner line of 25 km to reduce the area that had to be drained. A total of 100 km of dikes were constructed by 30,000 men. Similar to the building of the pyramids in Egypt. The route has signposts"Line 1629\\\".  It goes through a great diversity of landscapes and nature reserves and consists almost entirely of cycle paths.
