As the name suggests, it was forbidden to enter this city for over 500 years. The Forbidden City took 14 years to build, from 1406 to 1420, and it took 1,000,000 workers including more than 100,00 craftsmen to finish the entire city. This city was the imperial palace of China for 492 years after it was built. Covering 0.72 sq km (0.28 sq mi), of which 15 hectares (38 acres) are floor area, this city was home to 24 emperors, 14 of the Ming dynasty and 10 of the Qing dynasty.
This incredible settlement has 980 buildings in over 70 palace compounds, with over 8,700 rooms, and it’s surrounded by a 10-meter-high wall, which is 3.4 km (2 miles) long. The whole reason this city was build was because of a scandalous coup d’état plotted by Zhu Di, the fourth son of the Ming dynasty’s founder Zhu Yuanzhang, that made him the Chengzu emperor (his official title) in 1402. In order to solidify his power, the Chengzu emperor moved the capital, as well as his own army, from Nanjing in southeastern China to Beijing and began building a new heart of the empire, the Forbidden City.
