This delightful "cottage orné", or ornamental cottage, was built in the early 1800s by Richard Butler, 1st Earl of Glengall. Based on a design by the famous Regency architect, John Nash, and inspired by nature, the cottage's unusual and rustic features include a distinctive thatched roof while its external woodwork resembles branched trees. The nature theme is continued throughout the former guest cottage's internal furnishings and wallpaper. Its interior contains a graceful spiral staircase and some elegantly decorated rooms. The wallpaper in the salon, manufactured by the Dufour factory, is one of the first commercially produced Parisian wallpapers. Swiss Cottage is situated on an elevated site with access by stone steps.
