Mongchontoseong (Korean : 서울 몽촌토성 ) is an ancient earthen rampart dating from the Baekje period.[ 1] It is located what is now in the Olympic Park of Seoul , South Korea.
The fortification walls are estimated to have been about 2.7 km (1.7 mi) in length and approximately 6 to 7 m (20 to 23 ft) high. The fortifications of Mongchontoseong had a palisade atop the wall and a moat surrounding its base. They are part of Wiryeseong with Pungnaptoseong .
During the 1988 Summer Olympics , the running section of the modern pentathlon was held there.[citation needed ] A number of important excavations of the site were conducted prior to the construction of the nearby Olympic Park.[ 1]
