Superb historical excavations What a brilliant experience guided by the very knowledgeable Tom. What he doesn't know about the tunnels and the history isn't worth knowing. We only experienced the Paddington excavation which is probably less than one tenth of the whole system. Will definitely be booking on the main tour. The amount of discarded artifacts from the Victorian era onwards was fascinating. Well done to all involved. We even discovered that my wife is related to William Boote, the grocer who occupied several of the Williamson buildings!
