As the Biblical story goes, Moses parted water of the Red Sea to lead Israelites out of Egypt. While this sunken pedestrian bridge in the Netherlands does kind of the same feat with much less involvement of the supernatural, it still is pretty amazing. Designed by RO & AD Architects, the sunken bridge leads to a 17th century fort which was built as a defense against French and Spanish attacks.
The castle is surrounded by a moat that was too deep to march across and too shallow to deploy boats, and it now has this Moses bridge to boast. Made out of Accoya wood, the bridge is invisible to the eye from a distance, but becomes visible and apparent as the moat of castle Fort de Roovere is approached.
