The museum is in itself a sight to see. It's housed in four restored noble houses, and there are five floors you can explore here. The tour starts out at level 0, at which you are a few floors underground. The internal architecture is fascinating, and you will definitely be impressed. There are several multimedia displays throughout, and each one explains different facets of history. The museum explains the history from its' creation in the 10th century until the present day.
Fondest memory: As usual I was taking photos inside when a man came up and said that photography isn't allowed. Oh well, at least I got off about a half dozen pictures first.
