Document 10: List of castles in Greater Manchester: There are nine castles in Greater Manchester, a metropolitan county in North West England. They consist of four motte-and-baileys, three fortified manor houses, an enclosure castle, and a possible shell keep. A motte-and-bailey castle has two elements, the motte is an artificial conical mound with a wooden stockade and stronghold on top, usually a stone keep or tower. A bailey is a defended enclosure below the motte, surrounded by a ditch. Motte-and-bailey castles were the most common type of castle in England following the Norman Conquest. A shell keep was a motte with a stone wall rather than a wooden stockade on top; there would have been no tower within the walls. Four of Greater Manchester's castles are Scheduled Ancient Monuments: Buckton, Bury, Radcliffe Tower, and Watch Hill. A Scheduled Ancient Monument is a "nationally important" archaeological site or historic building, given protection against unauthorised change.
