The estate of Ann Walker

The estate of Ann Walker (Sophie Rundle), the neighbouring heiress who Anne Lister woos no longer exists so the TV crew used Sutton Park instead. This early Georgian estate, eight miles from York, is open to the public even though it's still the home of Sir Reginald Sheffield and his wife Lady Sheffield. The family once lived at what is now Buckingham Palace, and much of their art collection comes from there.
