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 held the lord's manorial courts, communal meals with manorial tenants and great banquets. The term is today loosely applied to various country houses, frequently dating from the late medieval era, which formerly housed the gentry.
They were sometimes fortified, but this was frequently intended more for show than for defence. Manor houses existed in most European countries where feudalism existed, where they were sometimes known as castles, palaces, and so on. Many buildings, such as schools, are named Manor; the reason behind this is because the building was or is close to a manor house.
The lord of the manor may have held several properties within a county or, for example in the case of a feudal baron, spread across a kingdom, which he occupied only on occasional visits. Even so, the business of the manor required to be directed and controlled by regular manorial courts, which appointed manorial officials such as the bailiff, granted copyhold leases to tenants, resolved disputes between manorial tenants and administered justice in general. A large and suitable building was required within the manor for such purpose, generally in the form of a great hall, and a solar might be attached to form accommodation for the lord. Furthermore, the produce of a small manor might be insufficient to feed a lord and his large family for a full year, and thus he would spend only a few months at each manor and move on to another where stores had been laid up. This also gave the opportunity for the vacated manor house to be cleaned, especially important in the days of the cess-pit, and repaired. Thus such non-resident lords needed to appoint a steward or seneschal to act as their deputy in such matters and to preside at the manorial courts of his different manorial properties. The day-to-day administration was carried out by a resident official in authority at each manor, who in England was called a bailiff, or reeve.
