more sophisticated, due to better construction techniques being developed.
The wall body: The Ming Great Wall usually had battlements 1.8 meters (6
feet) high with loopholes and crenels, and parapet walls 1.2 meters (4 feet)
high.
Flanking towers: Every 500 meters or less (1,640 feet) on the Great Wall there
was a flanking tower allowing defenders to shoot arrows at attackers at the
face of the wall.
Fortresses were built at important/vulnerable access points (passes), such as
Shanhai Pass Fortress, Juyong Pass Fortress, and Jiayu Pass Fortress. There
were many archery windows and gates on the forts. The fortress gatehouses
were the strongest and most impregnable structures on the Great Wall.
