Here is an excerpt from thier web page regarding the history:
Instead, events conspired to bring us here and the romance of their decay took a hold on our imaginations. Our discovery of a tiny room, buried under fallen masonry in the corner of one of the walled gardens, was to unlock the secret of their demise. A motto etched into the limestone walls in barely legible pencil still reads “Don’t come here to sleep or slumber” with the names of those who worked there signed under the date – August 1914. We were fired by a magnificent obsession to bring these once glorious gardens back to life in every sense and to tell, for the first time, not tales of lords and ladies but of those “ordinary” people who had made these gardens great, before departing for the Great War.
