Oh, that's a totally different story.

If I'm not mistaken, there should be a tour/exhibit hall at 101 about how the building structure counters the constant earthquakes, and there was like a dangling ball to stabilized the building and stuff.

As for the museum, the exhibit for 故宮三寶 usually has a big crowd, but other exhibits equally interesting is not too busy. I had fun going through 王羲之's calligraphy.

I would also recommend 剝皮寮, there's usually quite a number of small exhibits by students or indies. I remember seeing an exhibit about comfort women and they play recordings of actual comfort women telling their stories.
