Longleat, the residence of the Marquess of Bath, has been haunted for many many years. It is said that his ancestor, Thomas Thynne, 2nd Viscount Weymouth, had fought a duel in a passage at the top of the house with an unknown man, who was rumoured to be his wife's lover. He killed this man, and had him buried in the cellars of Longleat. The passage where the duel is said to have been fought is now known as 'The Green Lady's walk', and is said to have been haunted by the spirit of Lady Louisa Carteret, wife of this 2nd Viscount Weymouth.
When central heating was put into Longleat, during the 5th Marquess's lifetime, the body of a man was found buried in the cellars. He was wearing jackboots, which crumbled away as soon as the body was exposed to the air.
Lady Louisa Carteret, Viscountess Weymouth, died aged about twenty-two, after hree-and-a-half years of marriage and nine days after the birth of her second child. It was rumoured that Viscount Weymouth nearly ruined himself and his two sisters by his extravagance after the death of his wife.
