The west front was not built till about one hundred and fifty years after Richard II. had added a porch to the north transept, and thus completed the thirteenth-century façade. The inside of the nave had been slowly growing all this time, and early in the reign of Henry VII. the vaultings were at last finished, and the exterior carried up as high as the basement of the towers, under the supervision of two successive abbots, Esteney and Islip. We scarcely see the upper part of the towers in the illustration, but we can well dispense with them, for they were added under the auspices of Wren and his followers in the eighteenth century, and are by no means a success. Owing to the crumbling state of the stone used for the fabric in former days, this façade and the towers themselves have recently been refaced, and the pinnacles strengthened. To the right of the picture are the windows of the Jerusalem Chamber, in which room Henry IV. died. To the left, appear St. Margaret's Church and a portion of the north transept, whilst in front is a monument erected to the memory of those "Old Westminsters" who were killed in the Crimean War.
