Marco das Três Fronteiras Foz Do Iguaçu

Once little more than an uneventful obelisk, the Parque Nacional do Iguaçu concession folks have now built a small tourist complex around the viewpoint of all three tri-border countries that includes a children's park, a light and water show, cultural shows and a memorial to Álvar Núñez Cabeza de Vaca – the first European to have recorded the existence of the falls around 1540.
