Visited the O Street Museum in the Mansion today to see the "The Through the Looking Glass Exhibition" in the museum's secret gardens. So much to see... secret rooms, hidden passages.... Docents and staff were excellent - friendly and knowledgeable. Will definitely return... so much to see and secret rooms to find.

At 42 its hard to awake the 8 year old boy that dreamed of secret passages and blind doors, thoughts of spies and secret rooms but that's just what you did! I couldn't stop talking about it at work. I'll be back for sure.

Went to the O Museum in The Mansion for the tour. This tour included searching for hidden doors and gems through out the space. There are 70 hidden doors, but most that tour only find a small fraction of them. Normally less than 2. ;)Spent a few hours exploring and was able to find a few doors and a few hidden gems. 14 doors, and 2 gems. The Rosa Parks room was fantastic, to actually be in a space that she lived for over 10 years was epic. The entire mansion feels like a huge thrift/antique store. It has a ton of books, toys, dishes, you name it. The space is fantastic. It is a lot of walking and a lot of stairs, although you can take the elevator to each floor. Overall this was the most enjoyable tour we took while visiting the Nation's Capital.
