Infernetto is located in Municipio XIII in the south of the city near to Ostia Lido and the seaside, surrounded almost totally by the Castelfusano pinewood and the presidential estate, is connected on the north side from Cristoforo Colombo street (which is the northern border of this zone) to the rest of city.
Infernetto has an ancient history starting with the Roman empire. It was a big cultivated area but after the decline of Roman empire the land was abandoned for ages and become a wetland and malaric zone.
In the last centuries the land was inhabited by a few people that were living in thatched huts from a group of hunters or lumberjacks, but mostly were people that were making coal by burning the wood from the local forest in a stack covered by 40 cm of soil. Soon the coal from wood become the first economy in the zone to sell in Rome, the name Infernetto derives directly from this economy because during the 18th and 19th century one could see a big column of dark smoke in the sky, sometimes even from the center of Rome, made from the coal production (if translated to English the name Infernetto means "little hell".) during the fascist age the land was drained, and started growing up as a farm town, during the 70s, it started to growing up as an illegal residential area, and many people start to build up houses without government license and without any urbanistic plan, that's why now you will find many narrow streets, unsealed roads, and areas without any drinking water or sewers.
In the middle of 90s Rome city council started to claim the street for fixing up, and built new infrastructure and now in the 21st century Infernetto is one of the most developing areas surrounding Rome. Farm land is fast giving way to the concrete industry, and many houses, resorts and buildings are growing up!
