San Leucio is a district of Caserta, located in 3, 5 km Northwest of the city centre. It lies at an altitude of 145 metres above sea level and was formed around the old silk mill – UNESCO world Cultural Heritage site by UNESCO. The name of the district received on behalf of the Church of St. Lectures that once stood here.

In 1750, the year of the Neapolitan king Charles VII on the advice of his Minister Bernardo Tanucci chose this place for the realization of unusual social and technological experiment – integration model of production based on technical innovation and business needs. Prior to this there was a hunting residence of the Acquaviva family, now restored and known as the Palazzo del Belvedere. The Belvedere, from Italian means "beautiful view" - and hence really in good weather you can enjoy a wonderful view of Naples Bay and the Islands of Capri and Ischia.

The first time the San Leucio was a place of rest to the Royal hunting grounds and aqueduct, which was used for stock-water to the Palace Reggia di Caserta. Son of Charles VII, Ferdinand I built there own hunting residence – he was an experienced hunter and loved the splendor and luxury of the Palace weekdays. And here Carl and Ferdinand founded the silk factory. Later around it were built production buildings and residential houses, which was unusual for Europe of the late 18th-century. The project architect was Francesco Collocini – it was he who established the noisy looms near the Royal apartments, and the living room turned into a chapel for the workers. For them, we built houses, and soon this whole area turned into an industrial town in 1789, the year was a kind of a crown colony for the production of silk. The members of this colony were used in their work the most advanced technology known in Europe, and enjoyed certain privileges. For example, they had social contributions, the pension, the right to free secondary education. The king even wanted to turn the colony into a real town called Ferdinandea, but this project was never implemented due to the invasion of French troops. Despite this the San Leucio continued to grow, and during the reign of Napoleon.

The heritage of king Ferdinand vividly to this day: the local silk and textile production provide its products to elite foreign clients like Buckingham Palace, the White House, the Palazzo Quirinale and Palazzo Chigi. From the main square of San Leucio – Piazza della Seta, overlooking the Palazzo del Belvedere, which adjoins the factory.
