We have a whole working town as a museum in the Mother Lode, its Columbia, a gold mining town. Mystic Seaport has a whole bay and harbor as a working museum, called Mystic Seaport. Like Columbia, it has the old buildings, still plying the trades they did in days of yore. Printing, barrel making, clock works and so on. The star of the port when we visited in August was the restoration of a whaling ship, The Charles W.Morgan, though other rescue efforts go on at the same time.
