Hwaseong Fortress
Highlight • Historical Site
With a considerable length of 5099 meters, the wall originally served as a protective barrier for the entire city. 18 gates served as entry and exit into the fortress. During the Japanese colonial era and during the Korean War, the fortress was badly damaged. It was largely restored from the 1970s onwards.
In 1997, the fortress was added to the UNESCO World Heritage Site as a World Heritage Site.
The fortress is absolutely impressive and should not be missing in any trip to Korea. From Seoul you can easily and quickly take the local trains to Suwon.

Gwongeum Fortress
Highlight • Castle
Ensure you wear appropriate hiking shoes, especially in winter, as the trail to the peak does not get cleared of snow. Try to come in the morning, as it can get very crowded during the day.

Western Bastion I (Hwaseong Fortress)
Highlight • Historical Site
The Western Bastion I is located where the fortress wall is sharply bent between the Northwestern Corner Pavilion and the Western Artillery Pavilion. As this was an important defense point, the bastion was built very close to the corner pavilion.

Northeastern Watchtower (Dongbuk Gongsimdon), Hwaseong Fortress
Highlight • Historical Site
"hollow outpost." This is because a gongsimdon conventionally has no facilities in its tall brick tower apart from an inner staircase and arrowslits in the walls. In Korea, this kind of watchtower was only constructed in Hwaseong Fortress. There were originally three watchtowers in Hwaseong Fortress, but only two remain today.
The Northeastern Watchtower is the only cylindrical brick building constructed during the Joseon period. It consists of three floors and is topped with a pavilion. It is also called "Soragak," literally meaning "conch tower," referring to the shape of the spiral staircase inside. This watchtower was largely destroyed during the Korean War (1950-1953) and was reconstructed in 1976.

Busanjinseong Fortress
Highlight • Castle
Busan City Walls
Busan Metropolitan City Monument No. 7
Busanjin was a strategic military base where, in the 7th year of King Taejong's reign (1407), the naval command of the left-wing Gyeongsang Province was stationed to defend the southeast coast of Korea. In the 21st year of King Seongjong's reign (1490), Busanjinseong Fortress was built beneath Mount Jeungsan to protect numerous warships, naval forces, and supplies.
In the 25th year of King Seonjo's reign (1592), during the Imjin War, the Japanese general Mori Terumoto destroyed Busanjinseong Fortress and built the main fortress, Jeungsan Waeseong Fortress, on the summit of Mount Jeungsan, as well as a branch fortress (a fortress built outside the main fortress) on the southeast coast to defend the main fortress. After the war, in the 40th year of King Seonjo's reign (1607), the Joseon Navy relocated its base to Jiseong and renamed it Busanjinseong. The perimeter of the Busanjinseong fortress in use at that time was approximately 2.25 km. The four gates to the east, west, south, and north were Jindongmun (鎮東門), Geumrugwan (金壘關), Jinnammun (鎮南門), and Gujangru (龜藏樓), and a gate tower (a tall house or attic built on top of a gate) was built. At the top of the castle, at Jaseongdae, they also built Mangongdan in memory of Mansedeok, a Ming general who fought in the Imjin War.
Afterward, the castle was demolished during the Japanese colonial period as part of the urban development plan, and most of its original appearance was lost. However, in 1974, as part of the Busanjinseong Fortress cleanup project, the Geunchunmun East Gate (formerly Jindongmun), the Geumnu-gwan West Gate, and the Jinnamdae General's Platform were restored.
Busanjinseong Fortress is a site that preserves the 500-year history of the Joseon Navy and the ancestors who risked their lives to protect the country. It is also considered of great historical value, as it can be used to study the Japanese castle built during the Imjin War and the naval base built using the Japanese castle in the late Joseon Dynasty.
