The hall at Oakham is typical, as to its main features, of all others down to the end of the sixteenth century. That is to say, the hall was the principal room; it was entered through the screens; at the lower end were the kitchens, at the upper the family rooms. It was nearly always a lofty apartment of one storey with an open timber roof. The principal changes that took place in the room itself were the elimination of the pillars and the contriving of a roof to cover it in one span from wall to wall; the provision of larger windows, and especially of a bay window at the daïs end; the addition of a porch to protect the front entrance from the weather. The other changes which affected it were those which took place in the rooms at either end; the growth of the solar into a suite of rooms, and the provision of separate sleeping accommodation for the servants. By the end of the sixteenth century these changes had very materially affected the size and plan of the house, and they ultimately led to the extinction of the hall as a living room; but this development will be further considered in a later chapter. [Illustration: 17. Cothele House, Cornwall (time of Henry VII.). The Great Hall.] An illustration of a late hall (of the time of Henry VII.) is given in Fig. 17, from Cothele House in Cornwall. It shows the large window, the fireplace, and the start of the open roof. The daïs has disappeared, as it has in most old houses, but the door leading to the family rooms is visible in the corner. It gives a good idea of the appearance of a mediæval hall. All the changes which took place in the treatment of dwellings tended towards the increase of comfort. The growth, it is true, was slow, and if a modern critic were compelled to dwell in them, the difference to him between a house of the twelfth century and one of the thirteenth would hardly be perceptible; both would be intolerable. But gradually the number of rooms increased both at the upper and lower ends of the hall. The keep still survived in a modified form, and often formed the nucleus round which the rest of the house grew. At Stokesay in Shropshire, which dates from about 1240, or sixty years later than Oakham, there is still a keep, but it is almost detached from the actual house, and may have served as the final stronghold to which the inhabitants could retreat in times of stress. At Longthorpe in Northamptonshire, some two miles to the west of Peterborough, there is a very interesting though small example of a keep or peel-tower attached to the house, and forming an integral part of it. The house was built in the latter part of the thirteenth century, and has undergone many alterations; but the tower remains in good preservation, as also does a contemporary gable adjacent to it, the only remnant of the original house.
