One of San Leucio’s most renowned silk factories, the Antico Opificio Serico De Negri, was founded in the late 19th century and still sells its wares in the company showroom. Made using an archive of over ten thousand original designs, their fabrics are remarkable for their quality and uniqueness. It is no coincidence that they have been used in prestigious historical settings, such as the Quirinale (the Italian head of state’s palace), the Kremlin, the White House and the Vatican.
