Schalmdijk Barrier

The asparagus barrier
This article was last updated on Thursday, July 23, 2009
Type description: 1 meter thick reinforced concrete block, buried in the road and provided with 1 or 2 rows of I-piles, the asparagus. These posts could be inserted into recesses in the concrete (tubes). The tubes were closed with lids in peacetime, so that traffic was not hindered much by them. Placed asparagus could no longer be removed when the barbs in the tubes were unfolded.
Function: Closing off roads over the entire width for tanks and armored cars.
Year of construction: 1939-1940
Design: CITB, January 29, 1935
Details: There were three versions of the Aspergeversperring. Type 1 had a single row of piles, type 2 had two rows of piles in succession and type O for the Peel-Raamstelling. The latter resembled type 1, but was lighter. During (night!) exercises by the Dutch army, it turned out that a row of asparagus could be set in fifteen minutes.

This truck obstacle was to prevent (German) armored vehicles and tanks from passing the inundations over the high Schalmdijk.

Battery on the Schalmdijk is an earthen fortification of the Grebbe Line.
