“In 1874, Baron Ferdinand bought a farming estate from the Duke of Marlborough with money inherited from his father Anselm. He was familiar with the estate as he had seen it while hunting in the area. There was no existing house, park or garden, only a bare hill that had been stripped of its timber.[3] The foundation stone was laid on 18 August 1877, and the site was quickly transformed.”
