Home > Defensive wall

 
Defensive walls were common from the ancient period into the medieval period. Generally, these are referred to as city walls or town walls, although there were also walls, such as the Great Wall of China and the Atlantic Wall, which extended far beyond the borders of a city and were used to enclose vast regions.

City walls were still occasionally used as late as the 19th century although by this time they were generally of wood (rather than stone) construction and used only around small frontier settlements. City walls also had towers and were frequently surrounded by trenches.

The practice of building these massive walls had been developed sometime before the rise of the Sumerian Empire and was connected with the rise of city-states.
