In the age of Edward III. the castles differed from those of previous periods. The confined plan of the close fortress expanded into a mixture of the castle and the mansion; comprising spacious and magnificent apartments, the hall, the banqueting-room, the chapel, with galleries of communication, and sleeping chambers. The keep was entirely detached, and independent of these buildings. Such was the royal palace of Windsor, erected by Edward III.; and such were the splendid baronial castles of Warwick, Ludlow, Stafford, Harewood, Alnwick, Kenilworth, Raglan, and many others. The last-mentioned is one of the most perfect examples we are acquainted with, of the union of vast strength and security, with convenient accommodation and ornamental splendour. The keep is a perfect fortress in itself, and encircled by a range of minor towers and moat. Its masonry is unrivalled.[26]
Of one of these spacious castles we give a descriptive outline, chiefly from the paper read by Mr. J. H. Parker, on the visit of the Archæological Institute to Windsor, in July 1866. Amongst the royal and palatial edifices of Europe, that of Windsor holds a very high rank, and is, in a manner, to England what Versailles is to France and the Escurial to Spain; and while it is infinitely superior to both in point of situation, it far exceeds them, and indeed every other pile or building of its class, in antiquity. From having been the residence of so many of our kings, its history is, to a certain extent, identified with that of the kingdom itself from the time of the Conquest. The castle stands on an outlying promontory of chalk, commanding the winding shores of that part of the Thames, with a rich valley, which seems to have pointed it out as a natural position for a fortress in primitive times, when the natives wished to protect their country from invasion. The wide and deep entrenchments, and the high artificial mounds, indicate an early date. There are also roads at the bottom of the fosses, with a wide bank between them, on which several keeps were erected, first of wood and afterwards of stone. A subterranean passage leading from the bottom of the outer foss, at a depth of thirty feet, to the bottom of the inner foss, at a depth of fifteen feet (the present pantries), cut in a very rude manner through the solid chalk, has a vault of the time of Henry II. carried on chalk walls, built over a small part of it as far as the Norman buildings extended only: the doorways are of the same period, one of which is quite perfect, and opens into the inner foss. If Windsor Castle had been built in the fifth century by King Arthur, as was believed by Edward III. and the chronicler Froissart, the roads would have been on the level. They are more likely of the time of Caractacus or Julius Cæsar. Edward the Confessor is believed to have resided chiefly at Old Windsor, where some of the ancient earthworks certainly belong to a period before the Norman Conquest. William himself is said to have built a castle at Windsor, but there is no evidence of it. The Domesday Survey rather proves that there was one previously existing, which had been inhabited by Earl Harold in the time of the Confessor. Henry I. is said by Stow, writing in the fifteenth century, to have built New Windsor chiefly of wood; some of the fragments of stone carving found in the castle may be of his time.
