This ‘invisible bridge’ is located in the West Brabant Water Line region of the Netherlands, where inhabitants in the seventeenth century built a series of moats and fortresses to protect themselves from invasion. Made entirely of wood and waterproofed with EPDM foil, the bridge was commissioned in 2010 to form a passageway to the newly restored Fort de Roovere. “[It] can’t be seen from a distance because the ground and the water come all the way up to its edge,” RO&AD explain. “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.”
