Knights' plate armor was a type of protective gear used during the Middle Ages, primarily from the 14th to 17th centuries. Made from large metal plates, it covered the knight's body to defend against weapons like swords and arrows. The armor was designed to be both strong and flexible, allowing knights to move while remaining protected in battle. The construction of plate armor involved skilled craftsmanship, often featuring intricate designs and engravings. Each piece, such as the cuirass for the torso and gauntlets for the hands, was tailored to fit the knight perfectly. This armor became a symbol of chivalry and status among the nobility.
