In architecture , a hall is a relatively large space enclosed by a roof and walls. In the Iron Age and early Middle Ages in northern Europe , a mead hall was where a lord and his retainers ate and also slept. Later in the Middle Ages , the great hall was the largest room in castles and large houses , and where the servants usually slept. As more complex house plans developed, the hall remained a large room for dancing and large feasts , often still with servants sleeping there. It was usually immediately inside the main door . In modern British houses , an entrance hall next to the front door remains an indispensible feature, even if it is essentially merely a corridor.
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.
