Designated as Historic Site No. 10, the Seoul City Wall is an 18.627km-long wall surrounding Hanyang (present-day Seoul), formerly the capital of the Joseon Dynasty (1392–1910). The wall underwent regular repairs during the 500-year Joseon Dynasty. The wall itself yields evidence of the different skills and materials used, thereby giving it a significant historical value.
The Seoul City Wall Museum became full operational on July 31, 2014 after conducting partial operation since April. The museum displays historical artifacts relating to the transformation of the city, and has a permanent exhibition hall, special exhibition hall, information center and multi-purpose lecture room.
