Ramspol en de stuw

The bellows weir at Ramspol is an inflatable dam between the Ketelmeer and the Zwarte Meer. It is the largest bellows weir in Europe, built to protect the inhabitants along the Zwarte Meer against backwater in the Ketelmeer. The three bellows are each the size of ten terraced houses. Together they are 240 meters long. There is an information center at the bellows weir.
