A mediaeval wine window in Florence

 
These are still found in some older buildings in Italy, particularly in Tuscany. These small, hinged openings in the walls were traditionally used for the sale of wine and other beverages.

Wine windows have a rich history dating back to the Middle Ages and became especially popular during times of plagues, such as the Black Death in the 14th century and later outbreaks. During these times, wine producers would use the wine windows to sell their wine to customers without direct physical contact, reducing the risk of disease transmission. Customers would place their money on a small shelf outside, and the wine would be poured directly from a cask or bottle into their container.

In recent years, some of these wine windows have been rediscovered and restored, and they are sometimes used for their original purpose or as a nod to Italy's historical and culinary heritage. It's a unique and charming aspect of Italian cultural history and architecture.
