Gwanghwamun Gate begun its constuction in 1395 at the beginning of the Joseon dynasty. The gate quickly became one of the most important gates of the Joseon Dynasty since it guarded the main palace.
There are three other gates that can be found along the 2,404 meters (7,887 feet) of walls surrounding the palace. The other three gates are Sinmumun, Geonchunmun, and Yeongchumun.
The gate consists of three entrances and a towering two story pavilion. At one time, Gwanghwamun was guarded by multiple watchtowers.
