In a possible future, where mass nuclear reactions have brought the radiation levels of the planet to dangerous levels, people seek refuge to a quarantine beneath the earth’s surface. A new city under the city that is inhabited whenever there is an immediate need and whenever the conditions on the surface are not safe for the human health. This new city will compose a system of isolation from the rest of the world and it will provide its citizens the essentials for their survival until the surface becomes again habitable. In this new reality of pollution, the earth’s surface is transformed into a hostile environment for the human, who in order to protect himself must hide under the ground. There, in a closed and checked environment, the society evolves in order to suit the new laws for survival.

The shelter in the area of Lycabetus constitutes an example for underground shelters that are found inside mountainous forms. These become viable having applied techniques and methods  of underground mining, as those of underground marble quarries of Penteli, offering not only multiform spaces, but also protection. The location of the shelter allows for easy access from all the central regions of the city, providing protection and accommodation to about 40.000 residents. Initially designed as a nuclear shelter due to the recent events of radiation pollution in Japan, the shelter can also be used as a protection from other dangers, some of them being biological or chemical pollution, or even in the event of floods.
