What we do in fact see here is just two sides of the three-country area known as Triple Border. In the Google Earth photo here that I have copied and also offered the link so that you can go to the original site ( just click on the photo to enlarge and see source) , you can see the Paraná River as it winds down South past Itaipu Dam with the Acaray Island seen in midstream. To your left is Foz do Iguaçu, Brazil. To your right is Ciudad del Este, Paraguay. Linking both cities is the International Friendship Bridge dedicated in 1965. Still on your right you can see the Acaray River flowing into the Paraná river. A few kilometers downstream from the Bridge is the "Foz" or junction of the Iguaçu (Iguassu) River - or the point where the two rivers meet.
