One of the richest provinces of historical-geographical regions, emergencies and natural and artistic UNESCO protected sites. And ‘the province of Salerno. The northern part of the capital is divided into the end of the Amalfi coast (the southern coast of the Sorrentine Peninsula, UNESCO World Heritage Site) and the rear agro Nocera-Sarno, from the ashes of Vesuvius fertilized and irrigated by the river Sarno. Heading east is the capital, which develops at the point where the valley dell’Irno flows towards the sea, between the foothills of the mountains and the mountains Lattari Picentinis. Towards the south-east there is the large plain of the Sele or Paestum, until the twentieth century unhealthy and marshy land, today area with a high agricultural productivity and strong tourist attraction. Finally, to the south, over the Sele, we find large areas of the Cilento and Vallo di Diano, verdant and mountainous areas mainly of difficult access, long remained isolated from the main flow of traffic, but of great charm. On the territory there are numerous World Heritage sites recognized by UNESCO: the Amalfi Coast, the National Park of Cilento and Vallo di Diano, who is also a biosphere reserve and first Geopark, including the Italian national parks; the archaeological sites of Paestum and Velia (ancient Elea), the Certosa di Padula, the Caves of Perth and the Caves of Castelcivita.
