THE MYSTERIOUS CITIES OF GOLD ...
Is a French Animated series loosely inspired by two children's historical adventure books called respectively The King's Fifth, and Island of the Blue Dolphins. The animated series follows the adventures of three children called Esteban, Tao, and Zia; and is set in the 16th Century as Spanish Conquistadors invade and plunder the New World (The North and South Americas) in search of gold and glory. In particular they are after the fabled Seven Cities of Gold (also known as the Seven Cities of Cibola and based on a real legend). It is these seven cities that the series is centred around and a lot of history and culture is mixed with the science fiction technology of the cities of the series in a very exciting and adventurous way.
The series was first broadcast in 1982 and concluded with only one of the cities discovered but exactly thirty years later in 2012 the series was not rebooted but was actually continued and ran for another two seasons until 2020. The quality and story of the first series was carried over perfectly and the series concluded in truly epic fashion with the discovery of the final city. I would highly recommend this series to anybody who likes adventure and history with a science fiction twist and anyone who is interested in different cultures as the story takes place all over the globe after season one!
