This Standing Cabinet Is An Icebox
Does your cabinet have a tiny door with no apparent use? It’s likely an icebox, also called a cold closet. Iceboxes were twentieth-century devices used to store ice before electric refrigerators. Delivery people would place the ice in from outside so they didn’t have to enter the house.
Some iceboxes were built into portable refrigerators, while others were installed into cabinets. In the mid-twentieth century, developers added drainage systems to divert the melted ice from homes. Over time, mechanical refrigerators made an icebox unnecessary.
