Werk aan de Daatselaar

Here you see the Werk aan de Daatselaar with damsluis. This defense work of the Grebbe line involves the existing Slaperdijk in the line. The Grebbelinie was a front line of the Old Dutch Waterline and was built in the eighteenth century. These defenses had to protect the important cities in Holland against invaders by means of inundation (deliberate and controlled flooding).
