It is very old, for the See was established, or rather the cathedral was founded, by Peada, one of the kings of Mercia, which was one of the ancient divisions of England. It was destroyed by the Danes, and afterwards rebuilt as it is. It is 476 feet long, with transepts 203 wide, and has a central tower 150 feet high, ending with lofty turrets at the four corners. There are also two small spires at the ends of the great west front. This part forms a section 150 feet in height and breadth, and consists of three magnificent arches 80 feet high, surmounted by pediments and pinnacles, flanked by the small towers before named; and in this front the cathedral is peculiar. It was begun in 906, and at the time of the Reformation was considered one of the most splendid religious edifices in the kingdom. The interior is very grand and imposing. It is light-colored, almost white, having been restored, as it is called; which means that repairs have been thoroughly made in every part, and all washes, or tinted coatings, have been cleaned off, and as near as possible the work left in its original or natural color. There was a time, however, when all cathedrals had more or less of gorgeous decorations in fresco and high positive colors; next a white or tinted preparation covered all; and now, as that has been removed, more or less of the old frescoes show, but of course in a badly disfigured condition, and are only interesting as relics of another age. The probabilities are, the time will come when all will be re-frescoed in the gay colors of old. At the Reformation everything savoring of art, in the way of painting in churches, was condemned. A great reaction seems to be taking place, and the church has discovered that it is quite possible to use and not abuse these things; and in some instances artists were at work in cathedrals, painting small portions as specimens for re-decorating the entire work. Some examples of frescoed ceilings are already complete. Peterboro' is now very white and clean, and the effect of its great interior is most pleasing. It abounds in monuments, and many of them are of great antiquity and interest. Our statement must be so meagre that we dislike at all to enter the field of description, but will venture a little. Catherine of Aragon, first wife of Henry VIII., is buried here; and it is said that on account of the fact of this being her place of burial, the king was pleased to give orders that the cathedral be mildly dealt with, and so it escaped that destructive action that so much injured all the others.
