This estate is home to lush natural gardens and a museum which started out as a family home. H.F. DuPont was to bring it to its glory as a museum in 1951. He rescued in interior architecture of american homes. He installed these rooms and decorated them with items which might have been found in homes of that period. Fascinating!
Until January 2014 a separate exhibition is available which showcases costumes of Downton Abbey. See the maroon dress which Lady Mary wore when she was proposed to among other items.
