The interior of St. Margaret's is far superior to the exterior, a reversal of what is usual in church architecture. The splendid arcades of aisle arches, early Perpendicular, or transition from Decorated to the Perpendicular style, are uninterrupted by any chancel arch, and with the clerestory windows sweep from end to end of the building. The east window is filled with stained glass of the richest tints, the blues and greens being particularly striking. This glass has a history. It was made at Gouda in Holland, and was a present from the magistrates of Dort to Henry VIII. for the chapel of Whitehall Palace. The King, however, gave it to Waltham Abbey (doubtless in exchange for something else). The glass suffered many removals and vicissitudes, being at one time buried to escape Puritan zeal, but it was eventually bought by the churchwardens of St. Margaret's for 400 guineas. The aisle windows, with one exception, to be noted presently, are the work of Sir Gilbert Scott at the last restoration, just before 1882. He designed the tracery in accordance with what he conceived to have been the date of the church; but when his work was finished a single window, that furthest east in the south aisle, was discovered walled up, and the style of this showed that his surmise had not been far wrong, though the period he had chosen was a little later. The glass in several of the windows is of interest. That at the east end of the south aisle is the Caxton window, put up 1820 by the Roxburghe Club, as was also the tablet below. That in the window in the centre, west end, is in memory of Sir Walter Raleigh, who was beheaded in Old Palace Yard, near at hand. It was put in by Americans about twenty years ago. Raleigh's tablet, with an inscription copied from the old wooden one which dated from the time of his death, is near the east entrance. The Milton window, also due to the generosity of an American, is on the north side of the Raleigh one. One of especial interest to Americans is that to Phillips Brooks, Bishop of Massachusetts, near the vestry door. There are many others deserving of notice.
