Ming tombs
The gate historically known as the "Great Ming Gate", the southern gate to the Imperial City stands near the center of the square. It was renamed the "Great Qing Gate" during the Qing dynasty, and the "Gate of China" during the Republican era. Unlike the other gates in Beijing, such as the Tiananmen and the Zhengyang Gate, this was a purely ceremonial gateway, with three arches but no ramparts, similar in style to the ceremonial gateways found in the Ming tombs. This gate had a special status as the "Gate of the Nation", as can be seen from its successive names. It normally remained closed, except when the Emperor passed through. Commoner traffic was diverted to side gates at the western and eastern ends of the square, respectively. Because of this diversion in traffic, a busy marketplace, called "Chess Grid Streets", was developed in the big, fenced square to the south of this gate.
