Hallway

In architecture, a hall is a relatively large space enclosed by a roof and walls. In the Iron Age, a mead hall was such a simple building and was the residence of a lord and his retainers. Later, rooms were partitioned from it, and the space next to the front door became the entrance hall.

Today, the (entrance) hall of a house is the space next to the front door or vestibule leading to the rooms directly and/or indirectly. Where the hall inside the front door of a house is elongated, it may be called a passage, corridor (from Spanish corredor used in El Escorial and 100 years later in Castle Howard) or hallway.

In warmer climates the houses of the wealthy were often built around a courtyard, but in northern areas manors were built around a great hall. The hall was home to the hearth, and was where all the residents of the house would eat, work, and sleep. One common example of this form is the longhouse. Only particularly messy tasks would be done in separate rooms on the periphery of the hall. Still today the term hall is often used to designate a country house such as a hall house, or specifically a Wealden hall house, and manor houses.

In later medieval Europe, the main room of a castle or manor house was the great hall. In a medieval building, the hall was where the fire was kept. As heating technology improved and a desire for privacy grew, tasks moved from the hall to other rooms. First the master of the house withdrew to private bedrooms and eating areas. Over time servants and children also moved to their own areas, while work projects were also given their own chambers leaving the hall for special functions. With time, its functions as dormitory, kitchen, parlour and so on were divided off to separate rooms or, in the case of the kitchen, a separate building.
