Thursday August 8th 2019, we bought our tickets being told that 3 out of the 7 buildings were closed. In fact, another building was only partially available. Many rooms were closed for inventory. And another building was closed. So only 2,5 out of 7 buildings were visitable. Went to get a refund. Why don't they sell a cheaper ticket when only part of the museum is available? It is not very honest!
