Viata in subteran

Se spune ca sunt minuni naturale si in acelasi timp minuni aparute dupa interventia omului: sunt orasele si structurile subterane.

In lume gasim si astazi nenumarate astfel de orase, insa ele nu mai pot fi locuite. Astazi unele dintre orasele subterane ce s-au pastrat de-a lungul vremii se viziteaza. Mare parte dintre ele nu sunt destinate vizitelor turistice si nu putem stii cu exactitate numarul lor.

Derinkuyu Underground City

In Derinkuyu Turkey there is an underground city with 11 levels. It's able to hold 30-50 THOUSAND people. It has a wine cellar and stables for livestock. Each level has a huge rock circular door that can be shut from the inside to keep people out. It also has an air vent and pluming.

They say it was built/ dug in the 6th or 7th century BC. Thats a long time ago!
