Mongchontoseong Fortress, in Olympic Park in Seoul
In the area of Songpa, south of the Han River in Seoul, are remains of the Baekje Kingdom, notably two earth-wall fortresses and many relics from excavations there.
Mongchontoseong Fortress is inside the Olympic Park, a very large green park with wilderness areas, lakes and other interesting features, the main one being the Fortress.
Take the subway to the station of the same name on Line 8 and follow signs to World Peace Gate. Once inside the park there are big boards with maps and information to guide you round.
The Korean people have lived through a history of division and then unity, followed by more division and then unity. In the past, the peninsula was divided into smaller states and then was re-united by whoever was in power.
As a very brief summary, the major kingdoms of the past were the Goguryeo, Baekje and Silla, which were then united into the United Silla Kingdom. This was later followed by the Goryeo Dynasty, and then the Joseon Dynasty. The Joseon Dynasty lasted around 500 years and was the last unified kingdom before the Japanese invasion in the early 1900s.
We wandered around the park and along the fortress walls, reading the information boards, and later went into the new Seoul Baekje Museum. As we did this we began to get an idea, a picture in our minds, of what this ancient place was.
In the Three Kingdom Period on the Korean peninsula, the Baekje Kingdom was centered around this area of the peninsula, along the Hanggang River, as it was called then. Its main city/town was known as Hangseong. Archaeological excavations and research from Samguksagi (the Historical Record of the Three Kingdoms) are proving that Baekje had two capital earthen fortresses (sometimes called castles). The first, Pungnaptoseoung to the north, was built in the early Baekje Kingdom before the 3rd century, and was an important center of marine transportation. The second, Mongchontoseong a little south of the first one, is thought to have been built under the reign of King Geunchogo after the 4th century and served as a high fortress overlooking the entire area in case of a war. It was built at the end of a natural slope extending from Namhansan Mountain, and the natural landscape of the Hanggang River was used as part of the wall. So, it was here that Baekje was able to lay its foundation as a powerful kingdom.
We didn’t actually go to the Pungnaptpseong Fortress, but learned that this was where 30,000 troops of Goguryeo (one of the other Kingdoms) under King Jangsu attacked Hanseong, Baekje in 475. It is said that the castle surrendered after the 7-day attack and that Baekje King Gaero (reigned 455-475), who was in the southern section of the castle, tried to escape to the west, but was killed.
But, we spent quite a while rambling around what’s left of the Mongchontoseong Earthen Fortress. The place attracts many visitors, as it is a significant historical site and is pretty with fields of canola flowers, barley and grass. There are many walking paths, and we saw numerous working Koreans taking advantage of this space to walk during their lunch break.
As you walk along the top of the now-grass-covered earth walls you get a good view out over the park and to modern Seoul and huge groups of apartment buildings. In this park, too, we saw a number of squirrels and pheasants, and heard many other birds.
The fortress/castle is a 2.3 km-long earth fortress wall (about 1.4 miles), in a roughly circular shape, the walls ranging between 6-40 m (about 20-131 feet) high. The area inside the castle walls is 216,000 square meters (about 54 acres). Songnaecheon Stream flows along the walls and serves as a moat. A pretty bridge crosses at one point. This is the Gommal Bridge (Gommal-Dari). “Gommal” means a bridge found in a dream village. “Gommal”, derived from the archaic “Ggummaul”, is an old Korean word for “Mongchon”. The information board explains that “this classical and beautiful Korean word was given to this bridge in March 1986.”
Laid outside the castle wall are wooden barricades. Houses and other buildings have been
found here, along with storage pits and a pond. Thousands of pieces of earthenware, Chinese-made porcelain, bone, armor, and such, have all been unearthed here.
At one spot in the center of the fortress enclosure you find an ancient site of dug-out huts and some old tombs remaining, with stone chambers and soil mounds typical of the early Baekje period (200-475 AD). They are closed off, so you cannot actually get into them, but you can see where and how they were situated. Also found in the area was a hearth proving pre-historic habitation, as well as stone tables, fragments of stone swords and Baekje earthenware. These discoveries led researchers to believe that this area was a base for Baekje culture for a long period.
The small Mongchon Museum of History on the north side has historical relics discovered during the excavation of Mongchontoseong Fortress and Pungnaptoseong Fortress. Notable are some precious golden relics of the Baekje kings, a seven-pronged sword called Chiljido (that testifies to the outstanding iron-smelting skills of the time), and many pots. The history of human settlement here goes way back. The museum is free and open daily, except Monday.
There is much more to see in the Seoul Baekje Museum, also in the Olympic Park. More on that later.
