Chi are turret-like protruding sections placed at regular intervals along a fortress wall from which defenders could protect the fortress walls and drive back an approaching enemy. There are ten such structures at Hwaseong. The term chi, which literally means "a pheasant," was applied to these structures because pheasants are adept at hiding in grass and remaining watchful. Seosamchi is located between Seoporu (Western Sentry Post) and Seonamammun (Southwestern Secret Gate).
