The Chapel, dedicated to St. John the Evangelist, is a very rare, if not unique, example of such a large and complete apartment in a Norman keep. It is in plan a rectangle 40 feet by 31 feet, terminating eastward in a semicircular apse of its full breadth, making the total length 55 ft. 6 in. It is divided into a nave and aisles, a splendid example of Norman work, simple, complete. It was intended primarily, no doubt, for the devotions of the Conqueror and his descendants; the church of St. Peter below was built for the use of the garrison. Though architecturally plain, it was probably painted and hung with tapestry. Henry III gave some stained glass. The only fireplace in the great keep is on this floor. The Armoury was begun by Henry VIII. His original locality of the armour was Greenwich, and consequently there is little armour here older than the fifteenth century. It used to be kept in a temporary gallery, removed in 1883, on the south side of the keep; it was then removed to the top floor, and within the last few years the floor below is also required. I make no attempt to classify the armour here; the subject has been fully treated in the _Portfolio_ monographs, Nos. 33 and 38. South of the keep, between it and the ward wall facing the river, formerly stood the Royal Palace, which was removed at various times by James I and Cromwell to make room for storehouses. Some portions even remained until after the Restoration. The Castle Keep in the Middle Ages was the occasional residence of the lord, but he almost always had his ordinary lodging close by. In the plan will be observed “_k._ little storehouse in Cold Harbour”; it was the old gateway into the King’s residence, and the Queen had her own rooms between the Salt and Lanthorn Towers. At “_h._ Mortarpiece Storehouse” was the Great Hall where the King heard cases and received deputations. Of the twelve mural towers the _Wakefield_ is the most ancient. It is also known as the Record Tower, the national records having been kept there until they were removed to their present home in Fetter Lane. In the survey of Queen Elizabeth it is the Hall Tower, from its proximity to the hall just mentioned. It is a large circular building; the lower part is probably the work of William Rufus. The upper storey consists of a fine handsome chamber, with a recess which it is said Henry VI used as his private chapel, fitting it with aumbry and piscina; and tradition states that it was whilst he was praying here that he was murdered. The Wakefield Tower is now the receptacle of the King’s Crown and all the other splendid articles of the English regalia.
