Zona Espansione Nord, also known as ZEN or San Filippo Neri, is an economically deprived quarter on the northern outskirts of Palermo, Sicily. It is located in the VII municipality and has a population of around 16,000 people. It was constructed in 1969, under the design by architect Vittorio Gregotti, and it consists of bleak, multi-storied housing projects, most of which are in a state of dilapidation. As a result of rampant unemployment, poverty, high school drop-out rate and marginalization of the residents, ZEN has become notorious for its crime, juvenile delinquency, and social degradation.
