The city of Enna is set at the very heart of Sicily, perched atop a mountain, resembling an impregnable fortress. Standing at about 931 metres height, it has a cool climate even in the summer season. Its territory is endowed with natural resources such as the Rossomanno wooded area and the salt Pergusa lake, whose waters, according to mythology, witnessed the rape of Proserpine, daughter of Cerer, by Pluto. The Parco Minerario Floristella-Grottacalda, now a site of industrial archaeology, is located in the city vicinity; exloited up to few decades ago, the sulphur mines had been providing a major source of income and job.
