London Bridge
"On the south is a bridge of stone eight hundred feet in length, of wonderful work; it is supported upon twenty piers of square stone, sixty feet high and thirty broad, joined by arches of about twenty feet diameter. The whole is covered on each side with houses so disposed as to have the appearance of a continued street, not at all of a bridge.Upon this is built a tower, on whose top the heads of such as have been executed for high treason are placed on iron spikes: we counted above thirty".
