National Persian Gulf Day
Based on 'incontrovertible historical documents,' the body of water lying to the south of Iran is and has always been known as the Persian Gulf.
Certain circles of doubtful reputation have for some time tried to use a distorted name for the Persian Gulf, but it has never occurred to anyone, with even a superficial knowledge of world history or geography to call it by any name other than the Persian Gulf.
Iran plans to submit the Persian Gulf for registration as part of the country's Natural World Heritage Site.
Iran's Cultural Heritage, Handicrafts and Tourism Organization (ICHTO) believes the world registration of the Persian Gulf will help protect it from distortion.
