Fortified Tower

Medieval towers were defensive structures usually made of stone. Often they included battlements and arrow loops. Arrow loops were vertical slits in the wall where archers from the inside shot arrows through at the attackers, but made it extremely difficult for attackers to get many arrows back through at the defenders. A Battlement comprises a defensive low wall between chest-height and head-height, in which rectangular gaps or indentations occur at intervals to allow for the discharge of arrows or other missiles from within the defences. Towers can be stand alone structures or parts of defensive walls.
