Ventilation and Communication HolesThere are communicaton holes, not bigger than 10-15 cm in diameter, on the floors and the ceilings of the rooms between the various levels. Using these holes, underground city inhabitants did not have to walk through the long and tiring tunnels, they also could take defense precautions easily and quickly during times of danger. What they did about the toilet facilities is still unknown because in only two of the underground settlements, Tatlarin and Guzelyurt (Gelveri), are toilets fonud. In these settlements, there are living areas and even graveyards, to be used during the times of lenghty wars. However; whether these graves belonged to priests or important people is still unknown.
Inside the underground settlements, usualy connected with the lowest level, are shafts used for both ventilation and communication. These shafts were also used as wells. Some of the wells did not have access at the ground level, to prevent the enemy from poisoning the water supply.
Although some researchers claim that the underground settlements were connected to each other with tunnels, no conclusive evidence to support this idea has been found to date. |
