Plan on spending HOURS exploring this building of history. Every floor has something interesting and full of history in it and if there was a mason in your family, bring proof and they;ll look it up in the library for you if you call and make arrangements ahead of time. It's right across the street from the Alexandria VRE and King Street Metro so it's easy to take public tranport or the drive there. After you're done (we took 5 hrs) you can go on King Street and hit some restaurants or take the free trolley up and down King Street to find someplace else of interest like the Torpedo Factory.
