As the subject line says, what have you found during your remodel.  Mine has to be working on an old huge brick plantation style house.  This house had tunnels underground that led to different small buildings around the property, that was interesting but not the story I wanted to share about this home.  So we were going to add a sun room off the side of the house, problem was when I was in the basement measuring where to punch the mechanicals through we kept coming up 10' short of the outside foundation at ground level.  Come to find out it was a false wall, so we punched a hole through it and in the center of the room was a coffin with a certain symbol carved in the top of it, I will leave out the symbol for sake of causing arguments.  There was Wiccan artifacts on shelves all around the false wall as well.  Nothing was in the coffin, (thank goodness!) and it got donated to a local museum.  Even stranger, when we went to dig the footers for the addition we found hundreds of animal skeletons (sacrifices)  Needless to say, I couldn't wait to get that job done and get out of there.
