Sansepolcro owes sisters Adele and Ginna Marcelli the credit for creating in the early twentieth century a typical lace-making called "pin lace." This manufacture is handed down even to the present day thanks to the lace school with its educational courses. In addition to this inside the school you can visit an exhibition that collects lace catalogs, drawings on cardboard, technical tests of lace making, photographic documentation and much more. In short, the Lace Museum is another attraction to add to the list of things to see in Sansepolcro.
