A château is a manor house or residence of the lord of the manor, or a fine country house of nobility or gentry, with or without fortifications, originally, and still most frequently, in French-speaking regions.

A manor house was historically the main residence of the lord of the manor. The house formed the administrative centre of a manor in the European feudal system; within its great hall were usually held the lord's manorial courts, communal meals with manorial tenants and great banquets. The term is today loosely applied to various English country houses, mostly at the smaller end of the spectrum, sometimes dating from the Late Middle Ages, which currently or formerly house the landed gentry.
