Insaengmun is a modern gate built in the style of a Joseon-era fortress gate, standing on the road below the Dongnae Eupseong walking trail in Busan. The gate and the fortress wall leading to Dongnae Eupseong can serve as the starting point of the trail course. The fortress wall connecting to Dongnae Eupseong collapsed in 2015 and is currently under repair. Because the surrounding area is under repair, using the walking trail is inconvenient.
