William John Cavendish-Scott-Bentinck, 5th Duke of Portland (17 September 1800 – 6 December 1879), styled Lord John Bentinck before 1824 and Marquess of Titchfield between 1824 and 1854, was a British Army officer and peer, most remembered for his eccentric behaviour. A recluse who preferred to live in seclusion, he had an elaborate underground maze excavated under his estate at Welbeck Abbey near Clumber Park in North Nottinghamshire.^[1]
