The pulpitum is a common feature in medieval cathedral and monastic church architecture in Europe. It is a massive screen, most often constructed of stone, or occasionally timber, that divides the choir (the area containing the choir stalls and high altar in a cathedral, collegiate or monastic church) from the nave and ambulatory (the parts of the church to which lay worshippers may have access). Typically the pulpitum is lavishly carved and decorated, and those of York Minster and Canterbury Cathedral preserve complete medieval sets of statues of the Kings of England.
