Celtic shields
Celtic shields were usually oval or elongated oval in shape. They could also be round or hexagon shaped. On the front was usually a hollow wood shield boss to protect the hand. The boss was usually elongated to make the shield stronger and was sometimes covered by a metal plate. On the inside of the boss hole was a handle to hold the shield. The shields were made of wood, usually oak or linden (also called lime). Most often they were covered with leather.
