The Asschatterkade dates from 1745, and is one of the longest trenches of the Grebbelinie, with its length of 2500 metres. The trench from 1799 lies east of Leusden, at the edge of the flood plain. But there are also elements from more recent history which can be found.
The nine visible military bunkers, for example, were built during the mobilisation between 1939-1940. There is also a unique concrete tank barrier from this time. During the May Days of 1940, the Germans attempted in vain to break through the defences.
