Mega-mansion, art gallery or embassy?
The future for this nearly 27,000-square-foot residence is unclear, but rumor has it that everyone from high-net worth individuals to state embassies have stopped by to check out this once-in-a-lifetime property.
Originally built in 1914 as a residence, the mega-mansion was gradually converted into a home and gallery by its owner George Hewitt Myers, a rug and textile collector. Since Myer's passing in 1960, the two-mansion lot, which stretches the length of an entire city block, has been home to The Textile Museum.
And if you weren't already impressed by its history, the architect for this place? None other than John Russell Pope. If his name doesn't ring a bell, then perhaps some of his works may: the Jefferson Memorial, the National Archives' building and the National Gallery of Art.
