Updating the town walk for the Lucca chapter in my Italy guidebook, I was impressed at how many shops on the main drag had been in the same family at the same location for over a century. And this jewelry shop (with a storefront that completely folds up -- leaving just a green, wooden wall at night) has been in the Carli family for several centuries. In this video clip, as Signora Carli seems to guard the front door, Signore Carli shows off his very old-school safe.
