The Forbidden City has been a silent witness to history as the center of the Chinese empire and administration for the country's last two feudal dynasties. Home to the Palace Musuem, it is celebrating the 600th anniversary of its completion this year.

Here are photos of the Palace Museum taken by Li Shaobai and Su Tangshi, who have tried to capture the glory of its formidable walls and interpret the palace in their own ways.
