In architecture, a hall is fundamentally 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, so that today the hall of a house is the space inside the front door through which the rooms are reached.
Deriving from the above, a hall is often the term used to designate a British or Irish 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. Where the hall inside the front door of a house is elongated, it may be called a passage, corridor, or hallway. In a medieval building, the hall was where the fire was kept. 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. The Hall and parlor house was found in England and was a fundamental, historical floor plan in parts of the United States from 1620 to 1860.
