The reign of Edward III. is one of the most important in respect to the history of Windsor, a large part of the existing castle having been built at that period, and its survey has been lately brought to light. Another equally important document is the builder's account for the Round Tower, which was entirely built from the ground in the eighteenth year of this reign, and still remains, though much altered in appearance, from the additional story superposed by Mr. Wyatville, under George IV. This building is sometimes called the Round Tower, and sometimes the Round Table; and, from other peculiarities in the same accounts, it is evident that the tower was built to hold the table. The galleries on which this round table was placed are still remaining, and the general disposition of the apartment where the knights dined on St. George's day is well seen from the summit of the Round Tower. The tables of those days were seldom more than a few planks in width, and the guests sat round on one side, the other being open for the service of the attendants. The centre of this great round table, then, was designed for the latter purpose, and was open to the air, a passage communicating on a level from this central space to the kitchen on the top of the middle gate, which has thus acquired the title of the "Kitchen Tower." The tower and table were erected in ten months, the greatest haste being made in order that the new order of knights might dine here on St. George's day following. Edward III. did not build a chapel at Windsor, but only completed the one which had been begun by Henry III.; adding to it or rebuilding a cloister, a vestry, and other adjuncts. After the thirteenth year, when William of Wykeham was appointed clerk of the works, with a salary of one shilling a day, an entirely new hall, with a new suite of apartments and offices, was built in the upper bailey, where the royal apartments now are; and the fine series of vaults under these apartments, forming ceilings to the servants' hall and other rooms and offices, still remain in perfect preservation, as built by Wykeham, who remained in this appointment only six years. The summary of his accounts during that time shows an expenditure of 5,658_l_.--equivalent to 120,000_l_. (?) of our money.
