It is in Lesa, in the Erno river valley, that it sprouts and realizes the idea. Giuseppe Marenzi with his wife Alessandra Diana, take over an ancient factory near the stream which, a source of natural energy, has already fed spinning since the early 1900s. They start their manufacture there by calling the Herno company, as a tribute to the river, because that story is inspired by water and the surrounding environment, still today a solid point of reference in the Herno universe.
