The Mansion on O & O Street Museum

With over 100 rooms and 80 secret doors, O Museum in The Mansion is one of the most unique experiences in the world.

O Museum was 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.

The only museum of its kind, you'll search for secret doors (they have over 80 of them!) and find your way through themed rooms, and covert passages to a world never experienced. You'll be walking in the footsteps of presidents and freedom fighters, historians, authors, artists and musicians, athletes, scholars, and many more.

Their unique exhibits promote and embrace life, from every culture, resulting in a wide-ranging collection. Here you will find original artwork by Mersad Berber, Frederick Hart, Gerald Johnson, and others; sports, music, and movie memorabilia like Bob Dylan's signed guitar from his Rock Roll Hall of Fame induction, Miss USA's crown, Prince's Purple Rain Jacket, the flag that flew over Merrill Lynch during 9-11, and an original letter written by John Lennon.

O Museum offers an immersive, tactile experience making it one of DC's most unique attractions. Guests will leaf through manuscripts, touch sculpture, hear rare studio cuts, and journey through an array of diverse architectural styles and exhibits like the Log Cabin, John Lennon Suite, Safari room, and Mrs. Rosa Parks' room (they were her home-away-from-home for nearly 10 years).
