Reflexiones sobre las métricas en Internet: ¿qué medir y cómo?
Derinkuyu is a mysterious underground city that was found in Turkey 1963. It's 11 stories deep and was made to accomodate 20.000 people. Scientists believe it was built 700 years BC. The city could be shut from the inside with large, round stone doors, but what people where trying to protect themselves from is unknown. It's likely, however, that Christians for a period used the city to hide from the Romans. There are also theories that the city was used as a hiding place from the aliens.
