pagan places

I've been thinking about the christianization of pagan places and feeling a bit frustrated by my lack of knowledge. There are some examples (like Knowlton and Rudston) where a church has been built in a place that obviously had some kind of significance already. But there are also places that are *thought* of in this way but where the history is difficult to prove and, indeed, disputed. For example, there are quite a lot of 'holy wells' in Britain which are dedicated to one or other saint. There's a commonly held belief that these were 'stolen' by early Christians and were originally pagan sites. But some historians have suggested that this is a myth propagated by different people for different purposes. This includes the neo-pagan movement, so - in an odd way - it may actually be that it is paganism that is appropriating Christian sites rather than the other way round. I gather that the historian, Ronald Hutton, has written about this kind of thing, so I'll see if I can get hold of his book on the pagan religions of Britain.
