It is to John's son, Henry III., that the present aspect of the castle is due, for though walls and towers have been rebuilt since his time, the general appearance remains the same. He was the first great builder, and beginning early with a reign of over fifty years before him, he was able to carry out his extensive building schemes. Deserting the Upper Ward, where all his predecessors had lived, he built his palace on the Lower plateau, also erecting a chapel on the site of St. George's. Less than a century after his death palace and chapel had vanished, fallen into a rapid decay, so that almost the only records of his work to-day are to be found in the Curfew Tower, and the Cloisters. The first King to be born at Windsor was Edward III., who spent great sums upon his palace, practically rebuilding the whole castle. Being a great warrior, loving war and glory, he became enamoured with the idea of founding an Order of Knighthood that should become as illustrious as that of King Arthur, who was believed to have some connection with Windsor. A Round Tower was built upon the mound, to hold the Round Table, and great festivities were held there in 1344, but this Round Table idea forms no part of the great Order--the Order of the Garter--instituted in 1348. It is thought that Froissart confused these two celebrations. [Illustration: Windsor Castle: Entrance to the Horseshoe Cloisters.] Under the superintendence of William of Wykeham, afterwards the great Bishop of Winchester, but employed by Edward III. as his surveyor of works, the Lower Ward was entirely given up to the service of St. George, the patron saint of the new Order. This involved the building of a new palace, which was erected upon the Upper Ward, hitherto merely walled and left vacant. At the time when these great building schemes were in progress, there were two captive Kings within the castle, for Edward did not entirely devote his energy to palace building, which merely formed a pleasing interlude to the long and ambitious wars which occupied his life. David II. of Scotland had been captured at Neville's Cross in 1346, and ten years later John, the King of France, joined him at Windsor, having fallen to the Black Prince at Poitiers. It is said that Edward, while walking with his prisoners, discussed with them the building of his new palace. They suggested that it would look more regal if it stood upon the Upper Ward, at which Edward cynically remarked that it should be erected at the cost of their ransoms. But as King John's ransom was never paid, and Scotland was too poor a country to provide much even to redeem their King, Edward was obliged to do most of the paying of the bill himself.
