A French term for a wall built across a ditch or fortification, with a sluice gate by which the height of the water in the ditch on both sides may be regulated. To prevent this wall from being used as a passage across the ditch, it is built up to an angle at the top, and armed with iron spikes. To render the attempt across still more difficult, a tower of masonry is built upon it.
