The largest room in this Manor House was added by Dr. Tennyson: it is the dining-room, with an open Groined roof; and the walls of it are now covered with apparently old paintings-heirlooms, one may suppose, of the Burton family.

During the twelfth and thirteenth centuries the roofs were often richly Groined, and upheld by cylindrical columns or clustered piers, and furnished with handsome bases and decorated capitals.

The Groined roof, though posterior to the original date of the building, is perhaps of the thirteenth century.
