Moored below Plaza Castilla is the diverting new Historical Ships Museum, on a 1906 Amazon riverboat, the gorgeously restored three-deck Ayapua . The exhibitions reflect the Amazon River's hodgepodge past: explorers, tribes, rubber barons and the filming of the 1982 Herzog movie Fitzcarraldo . Included in the entrance price is a half-hour historic boat ride on the river (Río Itaya out to the Río Amazonas proper).
