History Monitored: From ancient ruins and mysterious structures to lost cities

Explore a hidden world beneath Zimbabwe, revealing ancient marvels older than the pyramids. Great Zimbabwe, a city built from a million granite blocks without mortar, was proven medieval and African in 1929. Despite this, Rhodesian authorities suppressed the truth for decades.

Uncover thousands of ancient gold mines, a vast crack in the Earth holding platinum reserves, and some of the oldest dinosaurs. Discover the painted rock shelters in the Matobo Hills dating back 100,000 years.

Every site in this documentary is scientifically verified by archaeologists and geologists.

Highlights:

- Great Zimbabwe: The largest stone structure in sub-Saharan Africa, featuring the enigmatic conical tower.
- The Zimbabwe Birds: Eight soapstone carvings, looted during colonization, now reunited.
- Ancient gold workings: Linked to Chinese celadon and Persian glass trade.
- The Great Dyke: A platinum-rich geological formation.
- Victoria Falls: A natural wonder with a history of shifting gorges.
- Lake Kariba: A vast reservoir known for causing earthquakes.
