It is needless to state that there is no masonry at Windsor of the time of the Conqueror, or even of the time of his son Henry I., in spite of the statement of Stowe that Henry "new builded the castle of Windsor." This statement may perhaps be founded on a passage in the _Anglo-Saxon Chronicle_ which says that Henry held his court for the first time in the New Windsor in 1110. Perhaps the _Chronicle_ here refers to the _borough_ of New Windsor, as an entry in the _Pipe Roll_ of Henry I. seems to show that he was the first to enclose the _burgus_ of Windsor.[773] For it is probable that the first stone castle at Windsor was built by Henry II., who spent £1670 on it in the course of his reign. One of his first acts after his accession was an exchange of land at Windsor, which seems to have been for the purpose of a vineyard, and was possibly the origin of the second bailey.[774] At present the position of the motte is central to the rest of the castle, but this is so unusual that it suggests the idea that the upper ward is the oldest, and that the motte stood on its outer edge. Henry II. surrounded the castle with a wall, at a cost of about 128_l._[775] The other entries in the _Pipe Rolls_ probably refer to the first stone shell on the motte, and there is little doubt that the present Round Tower, though its height has been raised in modern times, and its masonry re-dressed and re-pointed so as to destroy all appearance of antiquity, is in the main of Henry II.'s building. The frequent payments for stone show the nature of Henry's work. Although so much masonry was put up in Henry II.'s reign, the greater part of what is now visible is not older than the time of Henry III. The lower bailey seems to have been enlarged in his reign, as the castle ditch was extended towards the town, and compensation given for houses taken down.[776] The upper (probably the original) ward is rectangular in shape, and with the motte and its ditches covers about 6-1/2 acres.[777] The state apartments, a chapel, and the Hall of St George, are in the upper ward, showing that this was the site of the original hall and chapel of the castle. The charter of agreement between Stephen and Henry in 1153 speaks of the _motte_ of Windsor as equivalent to the castle.[778] Repairs of the motte are mentioned in the _Pipe Rolls_ of Henry II.[779] The value of the manor of Clewer had fallen since the Conquest; that of Windsor, which was worth 15_l._ T. R. E., but after the Conquest fell to 7_l._, was again worth 15_l._ at the date of the Survey.[780]
