This museum is well worth a visit. You are directed to start at the rooftop sculpture garden and work your way down the 4 floors. The sculptures were impressive, maybe 8 feet tall and mostly of men doing traditional work. There were some wonderful paintings and smaller sculptures throughout the museum. I really liked that the paintings were grouped by themes, such as glass making, mining, road building, etc. Many of the paintings were European and so it was interesting to see the paintings from different countries over the years on the same working theme. We spent about 2 1/2 hours going through the museum.
