The Reclusive Duke of Portland

John Bentinck, the 5th Duke of Portland, lived an extremely reclusive life. For two decades, only a single servant had sight of him; not even his physician had access. He constructed a labyrinth of tunnels spanning 15 miles beneath his estate, featuring an expansive ballroom that never hosted any dances. Every space within his mansion and the underground tunnels was coated in pink paint.
