Foz do Iguaçu (in Spanish: Foz de Iguazú, "foz" - "mouth") is located in the far west of the state of Paraná, on the border with Argentina and Paraguay.
It limits with the cities of Ciudad del Este in Paraguay and Puerto Iguazú in Argentina.
The main sources of income are tourism and electricity production.
Among the attractions are the Iguazú Falls, the Itaipu hydroelectric dam and the Triple Frontier, which is the place where the Iguazú River has its mouth in the Paraná.
Foz do Iguaçu is considered a multicultural city with a large number of immigrants from different countries, such as Italians, Germans, Lebanese, Chinese, Ukrainians, Japanese and from neighboring countries (Argentines and Paraguayans).
In the 17th and 18th centuries, the place where the current Foz do Iguaçu is located was the seat of the Hispano-Jesuit locality of Santa María del Iguazú; the Portuguese and Brazilian bandeirantes destroyed it; then it was not until 1914 that the current city was founded at this strategic point.
