I used to live in Aarhus, well just outside it a few kilometers south in a town called Tranbjerg. I visited "Den Gamle By" (The Old Town) where there are historically valuable buildings from variouse locations in Denmark. These buildings have been un-assembled, moved to Aarhus and re-constructed. It is a part of our (Me no, I'm not a Dane) but for my new and accepted country men it is a very important to preserve such buildings. You could describe it as an open Museum.
