Hillwood, the former estate of Marjorie Merriweather Post (of Post cereal fame) and her third husband, the ambassador to the USSR, contains the biggest collection of Russian imperial art to be found outside of Russia. Post convinced Stalin and the Soviets to sell her loads of Czarist swag, and her impressive collection includes furniture, paintings and a shockingly gorgeous collection of Fabergé eggs and jewelry. As a bonus, the 25-acre estate incorporates some lovely gardens (which include Post’s dog cemetery), a greenhouse and a museum shop. The on-site cafe serves up Russian treats (borscht, blintzes and the like) and afternoon tea.
