The Verrerie de Biot in the Alpes-Maritimes department is, by far, the most visited company in France, with an average of 580,000 visitors per year. These visits are essential for its turnover as they ensure the longevity of the company and the transmission of blown glass craftsmanship. As the last artisanal site facing the large industrial glass institutions, Biot has welcomed on site or indirectly trained all the artisans practicing blown glass in France.
