A small number of motte-and-bailey castles were built outside of northern Europe. In the late-12th century, the Normans invaded southern Italy and Sicily; although they had the technology to build more modern designs, in many cases wooden motte-and-bailey castles were built instead for reasons of speed. The Italians came to refer to a range of different castle types as "motta", however, and there may not have been as many genuine motte-and-bailey castles in southern Italy as was once thought on the basis of the documentary evidence alone. In addition, there is evidence of the Norman crusaders building a motte and bailey using sand and wood in Egypt in 1221 during the Fifth Crusade.
