As you walk under the Curfew Tower, the Garter Tower, the Salisbury Tower, in Thames Street, only the mass and outline announce antiquity; the streets, the names over the shops, even the old man who has dyed his white beard to get work as a scaffolder, look more ancient. Doubtless the jackdaws, gliding straight out into the clear air from the Round Tower, have been there since Creçy, but the stonework is new. That also is the work of George IV. Except St. George's Chapel, the timber and herring-boned brick of the Horse-shoe Cloister, and the stone houses of the Military Knights where men obviously live, and the tranquil and leafy Canons' Cloister at the top of the Hundred Steps, most of the exterior of Windsor looks and is new. There is little foliage on the walls, very little moss and green mould, and small space given to the festoons of the bellflower, which contrives its ivy-shaped humid leaves out of the driest stone. The thrush sings with a clear, wild note that seems scarcely earned by the barren hard walls. Even if searched for, ancient buildings are not numerous or easy to find. Part of the lower story eastward from the Devil's Tower, and some foundations, are of Henry II's time. From Henry III's more survives--the outer wall on the west and its three towers, the wall of the South Ambulatory in the Dean's Cloister, a door behind the altar of the chapel, the remains of the _Domum Regis_ on the north of the chapel in one of the Canons' houses, and the King's Hall, now a library. The work of Edward III and William of Wykeham gives its form to the Castle as a whole. Of Edward IV's work St. George's Chapel and the Horse-shoe Cloisters remain. St. George's Chapel is the finest and most perfect survival from the Castle as it was at the end of the middle ages. Ruskin called it "a very visible piece of romance". It is exquisite and elaborate. It holds and embalms the sunlight. It might be called hard, and the nave and aisles are at first sight a little cold on account of the lack of history, except for the mildly pathetic monument to George V of Hanover. But the choir, with its pomp of banners, the swords, helmets, mantels, and arms of the Garter Knights, is of an incomparable sombre gorgeousness. The groined vault of the nave of St. George's Chapel, and the Tudor buildings on the north side, and the south and east walls of the Tomb House, are Henry VII's; the groined vault of the choir at St. George's, and the entrance gateway, are Henry VIII's. The gallery and façade, with the postern at the west end of the North Terrace, are Elizabethan. [Illustration: THE HORSE-SHOE CLOISTERS AND ST. GEORGE'S CHAPEL]
