Short and narrow Downing Street is the real centre of the British Empire, for the building numbered 20, looking very much like a cheap lodging house, has been the home of the Premier of England these two hundred years, since Robert Walpole was Prime Minister. Burial in Westminster Abbey is the highest mark of recognition and honour that can be bestowed by the English nation. In this grand old church have been crowned all the sovereigns of England from the time of Saxon Harold. Where the Abbey stands to-day there was once a church commenced by Sebert, King of Essex, in the year 610. It was on Thorney Island, the boundaries of which are not now traceable, for closely cemented partly by nature partly by artifice, it has become a solid part of the British Isles. The original church was later destroyed by the Danes. Another quite as large as the present one was begun in 1050 in the reign of Edward the Confessor and parts of this old edifice can be traced to-day. In 1220, Henry III. began the rebuilding of the Confessor's church but it was almost destroyed by fire before its completion. The damage was repaired by Edward I., and the church was added to by Edward II., Edward III., Henry VII., and indeed by all other sovereigns down to the year 1714, when Sir Christopher Wren undertook its complete restoration, adding the western towers as they are now. Perhaps no other spot in all the world is so truly holy ground and the number of the great ones of the earth sleeping here is very large. [Illustration: Interior of St. Margaret's, Westminster] Under the north walls of Westminster Abbey is the church of St. Margaret built during the reign of Edward I. on the site of an earlier church. William Caxton was buried in St. Margaret's in 1491. The fact that there was a chapel in the old Almonry where his printing press had stood led to the union branches of the printing trades being called "Chapels" even to this day. Sir Walter Raleigh is also buried here. The interest of St. Margaret's centres in a stained glass window made in Holland for Henry VII., setting forth the Crucifixion, which many times narrowly escaped destruction and was finally in 1758 purchased by the churchwardens and given its present resting place. The open space between Westminster Abbey and Westminster Hospital is the Broad Sanctuary so called because here in the 15th and 16th centuries was a sacred place of refuge for criminals who took advantage of the ancient protection of the Church. The Sanctuary was a square Norman tower containing two chapels. Elizabeth Woodville, widow of Edward IV., was seeking refuge here when her two children were taken from her and afterwards killed in the Tower by order of the Duke of Gloucester.
