Next to the road is the concrete block of the tank barrier which was part of the "Nieuwe Hollandse Waterlinie" (New Dutch Waterline) and also the "Stelling van Amsterdam" (Defence Line of Amsterdam). Steel asperes were put into holes in the block. A number of asperes are reconstructed.
The barrier was build in 1939-1940. Nowadays it is located next to the road, because the road itself was transferred recently.
