This shows a massive staircase that was closed off. Pictures really can't capture the experience.
Even the hinges were very detailed! These hinges were on some massive doors, probably 12+ feet high. The hinges were about 2 feet high each.
One very big house + kids = lots of "when can we leave????" requests. The adults were all too busy just absorbing the size of the place to pay any attention though and the kids finally gave up and just parked themselves on the floor.
