A mysterious medieval city in Africa had an amazing system to survive drought
It is not possible to estimate the exact amount of water stored by the dams around the city of Zimbabwe; Especially since the recent review is one of the first studies that really examines the structures. However, estimates show that these pits may have stored more than 18 million liters of water.
During the heyday of Great Zimbabwe (between the 11th and 15th centuries), this city was home to the ruling elite, religious leaders, artisans and merchants. These people shared spring and rain water in an integrated and flexible system.
According to experts, during the rainy season, some areas of this city become wet and swampy. The evidence indicates that these areas were suitable for extracting clay for use in house building. In the dry seasons, some mines have been used as reservoirs to collect underground water and runoff from the surrounding hills.
The authors of this article write in part of their report:
Currently, there is little information about the city of Great Zimbabwe. Even with such a carefully coordinated water system, it’s still possible that the city will fall apart due to climate change. Our world has experienced medieval climate anomalies and the Little Ice Age during its lifetime. All these events are factors that can put a growing city under severe pressure; Of course, economic or political pressures are also reasons that may lead to the destruction of such a city.
All in all, more research needs to be done before archaeologists can say what happened to South Africa’s first city and its people. Maybe there is a lesson in the ruins of this mysterious city.
