Plas Newydd, a 15th C mansion standing in spacious parkland just 2mi/3km southwest of Llanfair PG, came into the possession of the Earls of Uxbridge and later the Marquises of Anglesey in 1784. At the end of the 18th C the house was extensively rebuilt by James Wyatt, who also designed the very elaborate fan vaulting in the music room and the
hall. Among several museum pieces in the house are a mural by the English artist Rex Whistler and the patented "Anglesey leg", a wooden leg made for the first Marquis of Anglesey after the Battle of Waterloo. It was one of the earliest artificial limbs.
