Marjorie Merriweather Post was as silver and foxy as a lady can be.

Cereal heiress Marjorie Merriweather Post, who owned Hillwood from 1955 until her death in 1973, amassed imperial Russian art and 18th-century French decorative items. Her “outdoor rooms” — self-contained, themed gardens — were the toast of D.C. She adored her pets and gave them a sweet little cemetery. The force that ties it all together: her superhuman powers of good taste.

In the Russian Liturgical Gallery lies the Holy Grail … a grail that’s holy, anyway, and looks the part. Catherine the Great gave the jewel- and gem-laden chalice to a St. Petersburg cathedral in 1791. A crowd favorite is the 1833 painting “A Boyar Wedding Feast”: Look for the “problem relative” (every family has one!). Post owned two Faberge eggs; both are in Hillwood’s Icon Room. The prize inside the pink egg was, sadly, lost long ago: a toy figure of Catherine the Great, riding in a chair carried by two servants. Outside, the most showstopping space is the rose garden, designed by Perry Wheeler, who helped create the White House Rose Garden.
