The total length of Yuan Dadu City Wall Ruins Park is nine kilometers. The park does not have the majesty and grandeur of the royal garden, nor the open space of the vast grasslands of the forest park, but it contains the ancient history of the founding of the capital Beijing. In 1276, the city wall of Dadu in the Yuan Dynasty was built, with a base width of 2.4 meters. To this day, only the ruins of the northern section of the West Earth Wall and North Earth Wall have been preserved, and the Yuan Dadu City Wall Ruins Park was built on this basis. It is the largest urban belt-shaped park in Beijing, with the largest group sculptures and artificial wetlands in Beijing downtown.
