In Italy in the plague years of the 17th century, people installed tiny windows and doors in their walls at sidewalk level. Through these openings wine, beer, and spirits could be bought and sold without fear of contagion. (One account reported that patrons’ payment was collected in a metal scoop and the coins dumped into a bath of vinegar.)
These little openings are called in Italian buchette del vino. Three years ago the Wine Window Association (Italian site; Google translation) was founded to celebrate and memorialize this charming (if somewhat grim) architectural & cultural custom in Florence, Italy. It is, clearly, even more relevant now in this plague year of 2020.
Over 150 wine windows have been discovered within the city limits of Florence, some filled in or otherwise inactivated (here is a photo gallery). There are more within the greater Tuscan region. The Association keeps receiving news of new wine window discoveries throughout the country.
Over the centuries these architectural oddities have gone by many names in Italy, among them buche, finestrine, finestrini, finestruole, mostre, nicchie, porte del paradiso, porticciole, porticelle, porticine, sportellini, and tabernacoli.
