Athens kuchh pahaarr pe banaa hae. is built around a number of hills. Lycabettus is one of the tallest hills of the city proper and provides a view of the entire Attica Basin. The geomorphology of Athens is deemed to be one of the most complex in the world due to its mountains and causes a temperature inversion phenomenon which, along with the failure of the Greek Government to control industrial pollution, is responsible for the air pollution problems the city has recently faced. This issue is not characteristic of Athens alone; for intsance, Los Angeles and Mexico City also suffer from similar geomorphology inversion problems.
