St. Margaret's Church is traditionally said to have been founded by Edward the Confessor, and that there was certainly a church here before 1140 is proved by its being mentioned in a grant of Abbot Herebert, who died in that year. It was originally a chapel in the south aisle of the church of the Benedictine monks, and was rebuilt to a great extent in Edward I.'s reign. Further alterations were made in the time of Edward IV. In 1735 the tower was raised and faced with stone, and in 1758 the east end was rebuilt and the present stained glass inserted. A famous case between Sir Thomas Grosvenor and the family of Scrope concerning the rights of a heraldic device which either claimed was heard in St. Margaret's, and Geoffrey Chaucer, the poet, gave evidence. In 1549 Latimer preached in the church. The Protector Somerset, at the time he was building his great mansion in the Strand, had used a good deal of the ruins of religious houses, and still wanted more material. He therefore cast his unholy eyes upon St. Margaret's in order that he might use its time-worn stones for his own purposes, but he was resisted by the people of Westminster, who arose in their wrath and smote his workmen hip and thigh.
On Palm Sunday in 1713 the great Dr. Sacheverell preached in the church after the term of his suspension, and no less than 40,000 copies of his sermon were sold. The church was for long peculiarly associated with the House of Commons, as when the members began to sit in St. Stephen's Chapel they attended Divine service in St. Margaret's, while the Lords went to the Abbey. Edmund Waller, the poet, was married in St. Margaret's to Anne Banks on July 5, 1631, and John Milton to Katherine Woodcock in November, 1656. A son of Sir Walter Raleigh's is buried in the church, and also Colonel Blood. Children of Judge Jeffreys: Bishop Burnet, Titus Oates and Jeremy Bentham were christened here. Besides Latimer and Sacheverell the list of great preachers in St. Margaret's is long, including many Archbishops and Bishops, and the roll of Rectors contains many distinguished names. A man who occupies the pulpit must feel he has high tradition to uphold.
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.
