In Japan, I refrained masterfully from any 'architectural tourism'. We saw a lot, but I did not drag the family out of town to see this or that absolutely-must-see building. Maybe on another trip.
So I completely gave myself permission to go to Niteroi today to see the uber funky, iconic Contemporary Art Museum by Oscar Niemeyer.
This building is so refreshing, with clean lines and a great majestic entry sequence with the ramps. The galleries are simple and let the art talk. We had a great day.
