Type P
The Netherlands was preparing for a German invasion. Hundreds of Type P group shelters were built between November 1939 and April 1940. Characteristic of these Type Ps is the rectangular shape with three chamfered sides and a straight front wall. The sloping sides gave rise to the nickname 'pyramid'. The Type Ps are located in a meandering area of approximately 3 by 160 kilometers from Muiderberg, via Utrecht, Gorinchem and Dordrecht, to Goudswaard. They were intended as a group shelter, to shelter up to twelve Dutch infantrymen during the expected attack from Germany. However, the long line of concrete group shelters was never used.
Fascinating concrete blocks
Over 250 Type Ps have disappeared or been demolished over the years, until it was decided in 2009 to declare the shelters a national monument. For this publication, all 580 known and still visible Type Ps were visited and accurately mapped. The concrete blocks are a source of inspiration for artists and architects, who saw through, pack and even move the group shelters in their entirety. Flora and fauna also know where to find the Type Ps. They provide living space for bats, overwintering butterflies and special lichens. The versatile concrete block continues to fascinate!
