Medieval European stronghold, generally the fortified dwelling of the king or lord of the territory in which it stood. The castle developed rapidly in western Europe from the 9th century. In form it was somewhat sprawling compared to later fortified buildings. The castle's enceinte (outer wall) was surrounded by one or more moats, which were crossed by drawbridges that could be raised from the inner side. The gateway itself was heavily protected and often defended by a barbican, or watchtower. One or more baileys, or walled courtyards, surrounded the donjon. The age of the medieval castle came to an end with the increasing use of firearms in the 15th-16th centuries.
