The researchers established the main purpose of Derinkuyu: people were hiding here from dangers, mainly from religious persecution and raids of enemies. It is estimated that the underground city could accommodate 20 thousand people along with belongings and livestock.

Salt Copies of Turda, Romania

Salt mining here began in the days of the Roman Empire (albeit on the surface) and continued in the Middle Ages. In 1932, the mine was no longer used for its intended purpose due to obsolete equipment. The decision to turn Turda into a tourist destination was made in 1992, and by 2010 the Salt Copies of Turda had become a full-fledged tourist attraction. Tourists have access to:

Yerebatan Sarnici, Turkey

Date of construction - VI century AD. Today, a supply of clean drinking water is stored here in case of a city siege or drought. The structure is built in such a way that, in case of danger, water from 40 reservoirs will be supplied through the aqueduct directly to the city.
