The museum was previously a prison in Ushuaia. Most of the exhibitions are in old cells. The entrance offers manuals in several languages. The first part of the museum is the Maritime Museum area, where you can see models of several small boats and various pictures and information. The next part is the history of the indigenous people living in the area, and then you will come to a cell that introduces the prison. There is also a contemporary art centre, a small gift shop and a cafe (we didn't open when we visited). We spent about an hour here, but if you really do watch each exhibit carefully, it should take at least two hours.
