We really enjoyed our tour here. Tours are an hour long and with any luck you'll get to see all of the rooms targeted. Some may not be available depending on usage at the time so we were pleased to get into each. Our tour guide was great..very informative. He also paused for questions in each room. The building itself is as unique as a fingerprint. The stone and materials used to construct the building is as fascinating as it is to look at. The artwork is second to none, you're better off wandering this building than you are most art galleries. The best part of the tour?...it's FREE. Cheers.
