Describes the Forbidden City

I agree with the above answer, but it wasn't only a place for the emperors. It was reserved for the royal family. The Forbidden City was built in Beijing from 1406-1420. It is the largest palace complex in the world covering 183 acres and it compromises 9,999 buildings.

Lying at the city center and called Gu Gong in chinese, it was the imperial palace for twenty-four emperors during the Ming and Qing dynasties.
