Kakadu National Park, Australia (UNESCO)

Kakadu National Park is located in the Northern Territory of Australia and covers an area of 19.804 square kilometers. The park's name derives from a mispronunciation of the Aboriginal word Gaadudju. Aboriginals have been living in that area for over 40.000 years and thus  it is famous for the numerous Aboriginal cultural sites. In 1981 it was inscribed into the UNESCO World Heritage List.
