Moses Bridge in Halsteren, The Netherlands by RO & AD architecten

November 23rd, 2011 by Sumit Singhal

Article source: RO&AD architecten

The West Brabant Water Line is a defense-line consisting of a series of fortresses and cities with inundation areas in the south-west of the Netherlands. It dates from the 17th century but fell into disrepair in the 19th century. When the water line was finally restored, an access bridge across the the moat of one of the fortresses, Fort de Roovere, was needed. This fort now has a new, recreational function and lies on several routes for cycling and hiking.

It is, of course, highly improper to build bridges across the moats of defence works, especially on the side of the fortress the enemy was expected to appear on. That’s why we designed an invisible bridge. Its construction is entirely made of wood, waterproofed with EPDM foil. The bridge lies like a trench in the fortress and the moat, shaped to blend in with the outlines of the landscape. The bridge can’t be seen from a distance because the ground and the water come all the way up to its edge. When you get closer, the fortress opens up to you through a narrow trench. You can then walk up to its gates like Moses on the water.

    Do you have any details/photos of the actual construction of this bridge ?
    How was it built ?
    Was it constructed in place or fabricated on land and then set in place across the moat ?

      Hello Joe,
      If you send me your email, I will send you photo’s of the construction of the bridge.
      It is build by building 2 little dams in the water and than construct the bridge in between. So it was built in place.

        Thank you for your reply to my query about the construction of the bridge.
        As requested, I’m enclosing my e-mail address “” for you to send me photos of the actual construction.
        I also have another question: How is the bridge walkway relieved of rain water that would accumulate? How does it drain?
        Thank you again.
