Outfitted with antiques and furnishings from all around the world, guests can marvel at teakwood soaking tubs from Italy or a shower made from an English telephone booth. Discover unique hidden surprises in each room with over 70 hidden doors to explore throughout the property. The mansion has hosted CEOs, dignitaries, celebrities and scientists and has been the inspiration for a number of songs, paintings and even legislation crafted on-site.
