Mansion on O Street
With over 100 rooms and 70 secret doors, we are one of the most unique properties in the world. The Mansion was named #1 for meetings and events by Event MB and one of the top five historic venues to explore by Smithsonian Magazine. We have also been featured in numerous television shows, books and magazines including the Travel Channel’s “Mega Mansions”, National Geographic's Traveler Magazine, The Washington Post and The Washingtonian.
Rich in history your guests will enjoy exploring our themed rooms, searching for secret doors and browsing our museum's collection of manuscripts, books, art, memorabilia and signature guitars (we have over 50 including Bruce Springsteen, Bob Dylan, U2 & more).
We offer world-class cuisine, top-notch service and an inspiring environment that set the standard for out-of-the-box parties — from around the world food stations, to cigar rollers & scotch, to live performances, we have done it all! Together with our event planner we'll help make your dreams a reality. No request too large. No detail too small.
