The Mansion on O & O Street Museum

With over 100 rooms and 70 secret doors, The Mansion on O & O Museum is one of the most unique properties in the world. They were named "The Coolest Place in DC by, Top 5 historic venues to explore by Smithsonian Magazine, and Top 7 Hotels in DC by Forbes. Their immersive environment has been featured in television shows, books, and magazines including the Travel Channel’s “Mega Mansions”, and National Geographic's Traveler Magazine.

Meticulously designed with style & imagination the site retains many period details — including original tiffany stained glass windows and wood carvings. Ultra-private and secure, they offer a variety of themed rooms & suites, each uniquely decorated with fine art, antiques and furnishings from around the world. A haven for CEOs, rock stars, celebrities, and politicians, they offer privacy, security, world-class cuisine, and extraordinary service all in an environment that is nothing short of magical.

Steeped in history, it was converted into rooming houses for Hoover's G-men in the '30s. In the '60s Norman Mailer documented that student leaders of the protest movement lived there. From 1994 to 2003 it served as Mrs. Rosa Parks home-away-from-home and is a designated historic site on the African American Heritage Trail.

Visitors will enjoy an immersive experience that includes themed rooms, secret doors, history, art, literature, signature guitars, sports & entertainment memorabilia, and one-of-a-kind gems found only at O Museum.
