We were very much looking forward to seeing this museum. We went out there, despite our helpful hotel person telling us it was closed, because we looked on the website and there was nothing about it being closed. In fact, there was a message saying that after the holiday weekend (independence day), all activities would resume as normal. We took a taxi there and found the whole place under construction. There was a single small room open in the garden and nothing else. And no one to tell us if we just hadn't found the right room, no signs in English or Portuguese, nothing. Zero. Incredibly unhelpful for visitors.
