Here’s what you’ll learn when you read this story:Archaeologists working in the German city of Lichtenau have discovered a previously unknown subterranean medieval vault. The large vault is thought to have possibly been used for food storage or as a workspace for artisans who needed stable temperatures. Whatever its original intended purpose may have been, the Lichtenau vault may have also served as a shelter from the rampant feuds of the time. Vaults built during this era were often used as storage cellars for food, wine, and other goods. Dating the vault to the year it was built could link it to historical events that may or may not include feuds.
