Practical Info
Suggested DurationAbout 1.5-2.5 hours
Best TimeWeekend afternoons, or whenever you can book one of their signature 'Secret Door Hunts' or themed afternoon teas, are best. The property connects multiple historic townhouses filled with hidden doors and eclectic antiques, making exploration a thrill.
Getting ThereTake the Metro Red Line to the Dupont Circle station, take the South Exit, walk south on 19th Street to O Street, turn right, and walk about 2 minutes; the mansion is located between 20th and 21st Streets.
Travel Tips
- This is a massive maze consisting of 5 interconnected townhouses hiding over 70 secret doors. No walk-ins accepted; advanced online tickets for the 'Secret Door Tour' are required. Arriving over 15 minutes late results in immediate forfeiture with no refunds.
- Secret doors are hidden as mirrors, bookcases, or coat racks. Rule of thumb: Any door marked 'Private' or 'Staff Only' is an actual functional staff door—never touch them or you will trigger alarms. Genuine hidden passages bear absolutely no markings; look closely at floor scuff patterns instead.
- Nearly every single item you see inside (paintings, chandeliers, vintage guitars, furniture) is tagged for sale. If you break an item, you will be held financially liable based on its antique appraisal. Spaces are dim and cramped; large bags must be checked at the desk for a fee.
Reviews
Positive
- A thoroughly eccentric, magical, and unconventional experience! This bizarre labyrinth of interconnected historic row houses hides dozens of secret doors, making exploring highly thrilling.
- The mansion is packed from floor to ceiling with thousands of vintage antiques, rare guitars, and eccentric bric-a-brac; almost every single object on display is available for purchase.
- Rich in legendary alternative history; this venue famously served as a long-term residence for civil rights icon Rosa Parks, and every themed room carries an eccentric, storied past.
- The eclectic staff and characters on-site are incredibly warm and fun; they keep exploration completely safe while dropping just the right cryptic hints to help you locate elusive hidden passages.
Heads up
- Admission tickets are quite pricey, and because the layout consists entirely of narrow, clutter-filled rooms and steep, uneven stairs, it is functionally impossible for wheelchairs or strollers.
- Because of the sheer density of decades-old second-hand fabrics, rugs, and books, visitors prone to dust or mildew allergies may find the indoor air smells muskily heavy and uncomfortable.
- The dense visual layout is intentionally chaotic and cluttered with zero structured curatorial plaques; minimalist tourists might find the sensory overload feeling like an overwhelming flea market.
- They strictly enforce reservation arrival times; if you arrive late and miss the initial orientation brief, you will be forced to wait out in the tight entry hallway, which gets very cramped on weekends.
