Marking the end of the riverfront is the modern MAAC, a museum of anthropology and archaeology that hosts a superb permanent collection of pre-Colombian pieces and videos showing artistic techniques of early peoples. Changing exhibitions showcase thought-provoking works by contemporary Ecuadorian artists. MAAC also has a modern 350-seat theater for plays, concerts and films. We went on a Saturday, and despite the advertised hours, the museum was closed. Be prepared.
