When Was the Great Wall of China Built? A Quick History for First-Time Visitors

The Short Answer

The Great Wall of China was not built in one go, by one emperor, or in one century. First sections appeared as early as the 7th century BC, when separate states in northern China raised earthen walls against each other and against nomadic raids. Around 220 BC, China's first emperor Qin Shi Huang ordered those scattered walls linked into a single northern line. Most of the wall you can walk today, however, is much younger: it was rebuilt in stone and brick during the Ming dynasty (1368–1644).

If you only remember one date, remember this: the wall as a connected project is roughly 2,200 years old; the wall you actually visit is mostly about 500–600 years old.

The First Walls: 7th Century BC

Before there was one China, there were rival states, and several of them built walls. The earliest records point to the state of Chu building a square-shaped rammed-earth wall in what is now central China, followed by Qi, Wei, Zhao and Yan. These were local defensive lines, not a single border. Chinese histories date the earliest of them to around the 7th century BC, which is why any answer to "when was the Great Wall built" has to start there.

Qin Shi Huang Links Them: 220–210 BC

After unifying China in 221 BC, Qin Shi Huang sent General Meng Tian against the Xiongnu to the north and ordered the existing walls of Qin, Zhao and Yan connected into one continuous line. Forced laborers built and linked roughly 10,000 li (about 5,000 km) of wall and frontier works. It was not the stone wall of postcards — most of it was rammed earth, and large stretches were frontier fortifications rather than continuous masonry. The project cost enormous human toll, and it is the version of history that the phrase "the wall of Qin" refers to.

The Wall You See Is Ming Dynasty: 1368–1644

After the Mongols were driven out, the Ming dynasty rebuilt the northern frontier as a serious masonry project. Watchtowers, beacon towers and garrison forts were added; the core sections around Beijing — Badaling, Mutianyu, Jinshanling and Simatai — were rebuilt in stone and brick between roughly the 14th and 17th centuries. When archaeologists and the National Cultural Heritage Administration measured the total, they counted 21,196.18 km of wall across all dynasties, of which about 8,851.8 km were built in the Ming dynasty.

How Long Is It Really?

The most cited official figure comes from a 2012 survey by China's State Administration of Cultural Heritage: all walls built across every dynasty add up to 21,196.18 kilometers, including branches and parallel sections. The Ming-era core alone runs about 8,851.8 kilometers. Either way, it is the longest wall structure in the world, and it was inscribed as a UNESCO World Heritage site in 1987.

Which Section Should You Visit in 2026?

• Badaling — the most famous, most restored, most crowded. Best for first-timers who want the postcard view and easy cable car access.
• Mutianyu — slightly further out, greener setting, fewer crowds, with a toboggan on the way down. Golden Week 2026 data showed Mutianyu inbound orders nearly quadrupled year over year, making it the fastest-rising section for foreign travelers.
• Jinshanling — the photographer's pick: wilder, undulating wall with watchtowers that reward sunrise or sunset.
• Simatai — the only section open at night, with a dramatic lit stretch near Gubei Water Town.

All four are day trips from Beijing. Allow half a day for Badaling or Mutianyu and a full day for Jinshanling or Simatai if you want time on the wall itself.

Planning Tips

Go early (before 9 a.m.) to beat tour groups, carry water in summer, and book tickets online in advance through official channels or platforms like Trip.com. If you want the classic view with fewer people, pick Mutianyu; if you want night lights, pick Simatai; if you want the wildest walking, pick Jinshanling.
