Not many medieval kitchens have survived the years since their construction. One of the best preserved in Europe is the Abbot's Kitchen that still stands in the ruins of the Benedictine abbey at Glastonbury, Somerset. It dates from the second half of the fourteenth century and is, externally, square in plan. However, in each corner is a fireplace and this makes interior space octagonal, a shape that is carried through in the truncated pyramidal roof. The latter is surmounted by a tall lantern which itself has a tiny lantern on top.
