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.

My 25 year old daughter and my 14 year old great niece and myself(59) all had so much fun exploring the mansion! Fun for all ages all I could think about was bringing my best friend back or maybe coming to an event there some day.

Karen was wonderful & very helpful with suggestions in our search for the secret doors! .... we discovered 21 'verifiable' doors. Our group of 4 seniors had a blast for 3 hours exploring the house, and we will return. Thanks!!
