There's a new one written by Julian Richards, large format 50 pages at £4.99. As might be expected this is a much better guide than any of the old ones with some great illustrations, and the cover has fold outs that can be used to mark your place. It really is put together and presented very well, but it has the same old shortcomings. The restoration isn't detailed so you know what's what, and it is a very narrow establishment viewpoint - having said that they actually have half a page titled The Druids - there's a first !
