Gold flower at Forbidden Palace museum
The Forbidden City is called the Purple Forbidden City 紫禁城 (Zǐjìnchéng) in Chinese. It is the home of the Palace Museum 故宫博物院 (Gùgōng Bówùyuàn). In Beijing people call it Gugong 故宫 (Gùgōng), the Imperial Palace, for short. Those are easy to pronounce; if you click on the characters, you will hear a sound file.
The Forbidden City is the third imperial palace to have been built in Beijing. The first was built during the Jin Dynasty (1115-1234), the second during the Yuan Dynasty (1271-1368), and the Forbidden City was built during the Ming Dynasty (1368-1644). The Ming Dynasty began with protests against the rule of the Mongols of the Yuan Dynasty, so we will start our story there.
