Delphi was an important archaeological site in ancient Greece. It was considered the place where heaven and earth met. The temple of the Greek god Apollo was located there, and the Oracle of Apollo would provide advice and fortunes to kings and common people. Delphi also hosted the Pythian games every four years similar to the Olympics. Iguazu National Park in Argentina contains Iguazu Falls, one of South America's most spectacular natural wonders.
