The windows all have shutters. Not the decorative sort on many homes in my neighborhood. These are wooden, heavy, maintained and used. Sienna is a steep city on a hilltop. It is subjected to more wind and weather than others. Although the city abounds with modern amenities, shutters remain.
During balmy daytime they are thrown open and clasped to the outside wall with hooks resembling strong men. The clasp is pulled down to unhook shutters and the figure changes to a buxom female, to hang against the wall while families are safe inside from the dark or the storm.
I suspect that in narrow medieval streets, good shutters make for good neighbors, as good fences do in suburbia.
