Designed by the late, great modernist architect Oscar Niemeyer, the cliff-top Museum of Contemporary Art looks like a spaceship that has touched down to admire the views. The museum's visiting art exhibits tend to be underwhelming, but it's worth a trip here just to see the building. The museum is a five-minute cab ride from Praça Araribóia, by the ferry terminal in downtown Niterói, or take the 47B bus. The on-site bistro is a good spot for lunch.
