🤓 Fun Facts
The Octagon Room was designed by James Gibbs in 1720; most of the mansion was demolished two centuries later, leaving the Octagon and outbuildings.
The exiled future French king Louis-Philippe, Duke of Orléans, lived here in the early 19th century—hence the site’s name.
The gallery can host weddings inside the Octagon—baroque geometry meets modern confetti.
