Below the station at Tower Hill, some timber-piles were uncovered, which have been stated to be the remains of the scaffold on which Lords Kilmarnock, Balmerino, and Lovat suffered in the last century. But this seems unlikely, as no doubt the scaffold was removed after the last execution. But even if it was not, one hundred and forty years would hardly be sufficient to bury, many feet below the surface, so large an article as a timber scaffold. A rare and curious print, giving a view of Tower Hill on the occasion of the death of Lord Lovat, shows the scaffold about the middle of the Hill, and consequently to the south-west of the present station. Since the above was written, we learn that ‘more unexpected but important evidence’ has been brought to light of the buildings of ancient London, by the destruction of the remains of old London Wall. It had already been noticed that the foundations of the Roman wall by the river were made up very much of materials which had been already used in public buildings, and near to Tower Hill it has been discovered that some fine sepulchral monuments have been made to serve the same purpose. During the further destruction of the wall, it has been found to have been partly constructed with stones belonging to older buildings to a very great extent, some of the bastions being composed of them. In the wall in Castle Street, Bevis Marks, sculptured stones on which are inscriptions are being discovered, and carefully collected by some zealous antiquaries, for deposit in the Guildhall Museum. THE ‘STRONG-ROOM’ AT PETERBOROUGH. We have already referred (see _Journal_, page 464) to the singular revelation of a regular system of medieval ‘jerry-building’ found to have existed in Peterborough Cathedral; and we have now to record another interesting discovery, by which the old ‘strong-room’ of the church has been brought to light. In excavating for the foundations of the piers of the new central tower, some ancient masonry was found deep below the surface, which was at once pronounced to be the remains of the original Saxon church, which, together with the monastery, had been destroyed by the marauding Danes. These remains indicated that the former church occupied nearly the position of the present one; and whilst these antiquarian researches were going on, speculation was rife as to a certain crypt or chamber supposed to exist close under the floor of the present church, as indicated by Gunton, who wrote the History of the cathedral not very long after its narrow escape from the hands of Cromwell’s soldiers.
