Dutch Defence line 1940, Vesting Holland - Zuidfront, Numansdorp.
In the town of Numansdorp near the harbour, you find some Dutch bunkers called "Pyramide".
The bunkers, personnel bunkers, were part of a former Dutch defence line. The bunkers were built around 1940. All the bunkers can be entered, but they are in a bad state and one of them is completely burnt out.
3x Dutch Pyramide group shelter.
