The dovecote at Dunster, Somerset, is probably medieval in origin, perhaps built by the monks of the Benedictine priory. Its circular shape with no windows, an entrance door, and entrance from above for the doves, is widely used in such buildings, and this form was retained through the rebuildings of the C18 and C19.
The interior has 501 nest holes and it was from these that the newly hatched nestlings (called squabs) would have been collected to provide fresh meat. During winter the older birds were gathered to provide meat at a time of year when it was scarce. The rotating ladder called the "potence" allowed easy access to the holes.
