Casco Bay Island Compound
Medieval Castle in the Midwest
Gaudy Gilded-Age Mansion

Location: Washington, D.C.

Price: $6,900,000

This Hacienda-style house might look like something out of the Spanish countryside, but it actually sits next to the vice president's mansion on the grounds of the Naval Observatory in Washington, D.C. The $7,000,000 mansion hit the market back in April -- when our colleagues at Curbed DC took a look -- with just a few pictures of the innards, but it has since opened up about its wonky interiors. Now the listing photos include shots of a stub tile roof tucked into the catering kitchen, an uninspired media room, and some strange banquettes in the living room. Strange indeed, but, to be fair, this is the first time the stucco spread has been on the market in 50 years.
