Latest survey by the Beijing Municipal Administration of Cultural Heritage shows that there are 526.65467 kilometers of the Great Wall in Beijing.

Of the nearly 527 km of Great Wall, about 388 km have been renovated or rebuilt, according to figures released on Saturday, the fourth "Cultural Heritage Day", a domestic holiday that falls on the second Saturday of each June.

On the same day, the municipal bureau of cultural relics in Shanxi announced that there are 896.53 km of the Great Wall in the province, and 631.12 km of those have been rebuilt.

Data released by the State Bureau of Surveying and Mapping in April showed the total length of the Great Wall is 8858.88 km, nearly 71 percent of which have been rebuilt.

The Great Wall was originally built at the order of China's first emperor Qin Shi Huang (259-210 BC), who was also known for the Terra Cotta Warriors in his grand tomb, but most of the surviving walls were built in the Ming Dynasty, about 600 years ago.

The Ming Dynasty portions are scattered across 10 provinces in the northern part of the country. It starts in the northeastern province of Jilin and ends in the western province of Gansu.

The most visited sections, however, are the Badaling and Mutianyu sections in suburban Beijing.
