Castle tower medieval

Medieval castle towers, like this one captured by drone, were essential defensive and surveillance structures in feudal Europe, featuring characteristic crenellations and arrow loops.

About this subject

Medieval castle towers were central elements of military architecture between the 9th and 15th centuries. Built of stone or wood, they served as observation posts, fortifications, and often as the last redoubt during sieges. Iconic examples include the Tower of London and the Cité de Carcassonne, showcasing regional variations in design and function.

One of the most striking features of towers are the crenellations, alternating merlons and embrasures that protected defenders. Arrow loops, narrow vertical openings, allowed archers or crossbowmen to shoot while staying covered. Many towers also had sloping bases (batter) to deflect projectiles or prevent mining.

Tower height varied by need: keep towers (donjons) could reach 30 meters, like Rochester Castle in England. Smaller towers integrated into curtain walls were 10, 15 meters tall. Placement was strategic, enabling crossfire against attackers.

Notably, during the Gothic period, some towers gained residential and decorative roles, such as those at Château de Chambord in France, blending defense with Renaissance aesthetics. Modern drone surveys reveal construction details and medieval urban planning from unprecedented angles.
