Floodgate). Thanks to its elevated height, the pavilion serves as key lookout point, as much of Hwaseong and the area outside to the south and east can be seen from here. East Turret No. 3 (동삼치) Dongsam Chi, the third eastern turret, lies halfway from the south-east pavilion to the second eastern sentry post. Like other turrets, it extends a short distance perpendicularly from the wall to enable guards to see and attack assailants who had already reached the fortress. East Sentry Post No. 2 (동이포루) Dong-i Poru, the second eastern sentry post, like other sentry posts, is a wooden structure sitting on a turret. Construction of this post was completed on July 3, 1796 and it was intended to defend the beacon tower. For this purpose, it extends further out from the wall than the north-western sentry post. It also lacks wooden front doors. Beacon Tower (봉돈) Bongdon, the beacon tower, sits midway from Paldalmun to Changnyongmun. It is located intentionally in direct line with Haenggung so that the king could see its signals. Smokes and lights were used to signal the state of threats. The southernmost of its five chimneys was used during peacetime. East Turret No. 2 (동이치) Dong-i Chi, the second eastern turret, like the other nine turrets around Hwaseong, allowed soldiers to look out in many directions along the exterior of the wall. Unlike the other two eastern turrets, the outer corners of this structure are rounded, the others forming sharp right angles. East GunTower (동포루) Dong-GunTower, the eastern GunTower, lies between the two eastern turrets. Construction of the post was completed on July 16, 1796. As with other GunTowers in Hwaseong, the interior is of multiple levels to allow various angles for firearms and other weapons. East Turret No. 1 (동일치) Dong-il Chi, the first eastern turret, is the first turret south of the first eastern sentry post, lying along the wall towards the beacon tower. East Sentry Post No. 1 (동일포루) Dongil-SentryPost, the first eastern sentry post, was completed on July 10, 1796. Like the second eastern sentry post, it extends further from the wall than most posts. East Gate (창룡문) Changnyongmun, known locally as Dongmun (East Gate), sits by a major road junction. Its stone base is capped with a one-storey wooden pavilion. The gate was destroyed during the Korean War, but was reconstructed in 1975. North-East Crossbow Platform (동북노대) Dongbuk Nodae
