Jinshanling is a section of the Ming Great Wall in Luanping County, on the ridge that separates the Beijing plain from the Chengde hills. It was built and rebuilt in the sixteenth century under Qi Jiguang's command, and its watchtowers are close together, with brick chambers and arched windows. Part of the wall has been restored for walking; other stretches remain in the condition the weather left them, and the section is valued for showing both states side by side.
Jinshanling runs 10.5 kilometres along a ridge in Luanping County, Chengde, with five passes, sixty-seven towers and three beacon towers. Ming builders began it in 1570. Its first stretch has been returned to something like its original state; toward Simatai the wall is left to weather.
