You can't just walk into the Marijuana Mansion and light up a joint — the eccentric space serves as a photo-shooting gallery most of the time — but the historic, potentially haunted Capitol Hill mansion also moonlights as a private cannabis-friendly event host. Rooms are decked out with curated historic decorations and local art, giving each area an individual feel, ranging from Victorian to glow-in-the-dark, while the mansion's century-and-a-half history includes everything from spirit sightings to the creation of legal pot. Before the mansion's current owners took over, the building housed the offices of several attorneys who co-wrote Amendment 64, the voter-approved initiative that legalized recreational cannabis in Colorado. If you want to experience the Marijuana Mansion with a joint in hand, keep an eye on Eventbrite listings for private parties, and follow the instructions to request an invitation if you're 21 or older.
