Archeologists believe that the reservoir means that ancient tribes that once inhabited the region knew how to build complex hydro-technical facilities long before the ancient Greeks.
According to preliminary information, the reservoir was built between the 7th and 8th centuries BC, Dni.ru reported.
Right now the complex, consisting of several interconnected stone reservoirs, is filled with subterranean water.
Experts concluded that the complex was used as a natural filter for rainwater used by the ancients.
They also believe that the ancient reservoir could have been built either by Greek settlers or by Sinds – the ancestors of present-day Adygs, a people of the northwest Caucasus region.
