Numerous small iron plates excavated from the outer gateway were badly oxidized but x-radiography revealed their outlines and main features. They came from a jack of plate, a defensive garment consisting of a canvas doublet enclosing small plates stitched within it. Most of the plates were recycled from earlier protective garments such as brigandines, and plates were usually cut from old armor anyway. Wire hooks from the assemblage were probably fastenings for the jack. There is full discussion of parallels, artistic representations of the type, etc., and the reason for the deposit in the gateway (single garment or rubbish pile?). Date: mid-late 16th century?
