The 'motte' is a raised mound of earth crowned with a simple wooden tower, while the bailey is a larger area enclosed by a palisade of logs with a ditch outside. Sometimes the wooden components are 'pre-fabricated' off-site and brought with an army for rapid construction. Oddly, the word 'motte' eventually became 'moat', the deep trench around a castle rather than the man-made hill itself. |
