Have they found a cottage used by the Pendle Witches?

Well according to the BBC report there is a possibility they have!!
Whilst the Water Authority were doing some maintenance they found an old 17th century cottage under a mound of earth. No one knew it was there. The fireplace and several other features were remarkably preserved. They also found a mummified cat that had been bricked up in the wall. The suspicions are that it was bricked up whilst still alive. You can see the original report and video here.
