Historical Setting
By the time King Taejo established the Joseon Dynasty in 
the late 14th century, the country that we recognize today as 
Korea was a kingdom in turmoil. Ruled by the faltering Mongol 
Empire, under attack from Japanese pirates and weakened 
by political intrigues, the kingdom needed a strong leader. 
Yi Seong-gye, later to become King Taejo, was a talented 
general who repelled foreign threats, gained independence 
from the Mongols and established the “Kingdom of Great 
Joseon” in 1392. 
One of his first actions was to move the capital to Hanseong 
(Seoul) and initiate a building program that included a  
6.1 m (20 ft.) high and 18.2 km (11.3 mile) long wall to  
protect the growing city. Four major gateways were built 
into the wall to control access in and out of the city, and  
Sungnyemun would become the most impressive of these 
gates. Sungnyemun consists of an imposing stonework base 
and archway with a two-story wooden pagoda construction 
sitting above.
