We went there today for a look, and are looking forward to returning again soon. I've taken a few photos, including a set from the cellars, where paranormal researchers routinely carry out studies, as this is supposedly a "hot spot" for otherworldly activity. There just may be a ghost or two captured in the photos... if you spot one, please let me know.
Details of the property and its history are here- http://www.woodchestermansion.org.uk/HomePage.aspx. And if you want to see just how frightening this place can be, try the all night ghost hunt this Halloween! http://www.dusktilldawnevents.co.uk/halloween-in-woodchester-mansion-ghost-hunt-p-690.html
And now for the cellar. Again, if you think you see anything, let me know!
