The city of The Hague shows how you can preserve a bunker: incorporate it into urban design.
One of the three pre-war Dutch bunkers (which were part of the Atlantikwall during the war), was moved to the Army Engineers museum in Vught two years ago. Another was found but buried beneath the new boulevard. It’s however still visible. A thick glass plate covers the entrance shaft and the bunker’s building plan is visible on the pavement. A beautiful solution which shows that the historical value of bunkers is recognized more and more.
Photos and a 3D impression by Bas de Mos can be found on the website of the SAMS.
