Keep & Bailey Castle   Dico Tools
The castle which was developed from the motte & bailey castle of the Normans, dating from the late 12th and early 13th centuries. Consisting of a stone keep surrounded by a walled enclosure, the keep either incorporated or replaced the motte. Two types of keeps were used and they were; the shell keep and the square keep. This kind of castle however did not present a co-ordinated defensive system and thus had a noticeable military weakness. Once the bailey was taken by an enemy, the next part of the operation was to take the keep. The operation was made easier by the fact that the two components did not support each other; once the bailey fell to the enemy, all the enemy's forces could then be concentrated on the keep. See bailey, keep, motte, shell keep, square keep.
