These are organised in their relative direction to Old Stoney Bank and you might be able to enjoy more than one in a day in the same area depending on how leisurely you want to be. I will add a short description of each, in due course, to help in your planning, in the mean time you can link to each place's website (these will open in new windows so you can keep open those you are interested in). Some are in more than one section because they have a garden as well as a house or museum.
