Striano is an Italian municipality of inhabitants in the Metropolitan City of Naples in Campania, located in the Sarno Valley.
The city is located in the Sarno Valley, the south-eastern portion of the Campanian plain, a plain nestled between the Apennine Mountains, Vesuvius, the Lattari Mountains and open towards the Tyrrhenian Sea.
It borders Palma Campania to the north, Sarno (SA) to the east, San Valentino Torio (SA) to the south, Poggiomarino to the west and San Giuseppe Vesuviano to the northwest; the right part of the municipality is bathed by the Sarno river. The municipal territory extends over a surface area of approximately 7.58 km² and its altitude above sea level is between 30 and 16 meters (22 meters in Piazza 4 Novembre). In this area, which is not particularly large, a sustained demand for housing is being triggered. The municipality is part of the Sarno River Hydrographic Basin Regional Park.
The population growth from 1998 to today is due to the fact that following a flood in nearby Sarno, many people settled in Striano, to get away from the risk areas. Another factor is the immigration of EU and non-EU citizens, as well as the excellent geographical position that guarantees efficient connections with the provincial capitals, Pompeii, the Neapolitan, Amalfi and Sorrento coastal strip.
The nearest weather station for which data are available is Naples Capodichino. According to monthly averages calculated over the period 1961-1990, the average temperature of the coldest month (January) is approximately +8.1 °C, while that of the warmest month (August) is approximately +23.7 °C. The average annual precipitation is approximately 1000 mm.
There are conflicting opinions on the toponym of the municipality. The toponym Striano is of Roman origin. A fundus Histrianus is cited in the Velleja table and Striano is its apheretic form. In the Middle Ages we find the toponym Histricanum cited in the Bull of erection of the Diocese of Sarno of 1066. Traditionally it was thought that it came from Istra, an erroneous place of origin of Saint Severinus, the patron saint of the municipality. Recently, through studies and research, it has been demonstrated that the toponym derives exactly from the characteristic configuration of the Strianese lands called stigati, and from the way of working them.
