Many medieval rooms use stone vaulting supported by columns in the centre of the space, as used for other more utilitarian large rooms in monasteries with a generous budget. Others have much higher roofs. The shape of the room is usually designed to allow good audibility for speakers from all parts of the room. It may be rectangular, tending towards the square, but octagonal and other near-circular plans are an English speciality, with that at Worcester Cathedral probably the earliest.
