Why We Like This Place

  • The Mansion’s received plenty of accolades, including from the media: It’s been featured on the Travel Channel’s “Mega Mansions,” named a Washingtonian Magazine “Hidden Gem,” and written about in numerous best-selling books and prestigious magazines.
  • A long list of illustrious guests have stayed here. In fact, it was once home to Edward Clark, architect for the US Capitol, and his brother James “Champ” Clark, Speaker of the House (during Teddy Roosevelt’s Presidency), J. Edgar Hoover’s G-men in the 30s, and Mrs. Rosa Parks.
  • The venue itself is an irresistible adventure: Made up of 5 Dupont Circle row houses, it has 70 secret doors and over 100 rooms, many of them uniquely themed like the two-story Log Cabin, John Lennon Suite, and Safari Room to name a few.
  • Conversation-worthy, artistic pieces make the interior a visual delight. Everything on display—art, sculpture, memorabilia, chandeliers, even the signature guitars (they have over 50 of them)—can be used to dress up your event and are available for purchase.
  • They’ve got virtually every dream wedding scenario covered, thanks to a variety of galleries, alcoves, a ballroom, museum, hidden wine cellar, topnotch service, delicious food and a five-star pastry chef.
