Badaling is the site of the most visited section of the Great Wall of China, approximately 50 miles (80 km) northwest of urban Beijing city in Yanqing County, which is within the Beijing municipality. The portion of the wall running through the site was built in 1504 during the Ming Dynasty.
The portion of the wall at Badaling has undergone restoration, and in 1957 it was the first section of the wall to open to tourists. Now visited annually by millions, the immediate area has seen significant development, including hotels, restaurants, and a cable car.
