A breastplate is an element of armor that protects the chest and abdomen; it would have been worn with a now missing backplate. Nuremburg was one of the chief armor production centers and gained international renown; armor produced there was exported throughout Europe. It was not a coincidence that Nuremburg was known for its armor. The ore available in the region made Nuremburg an iron producing center close to the raw material needed to make a better quality and reliable product.
