“An-ding-men” (which in Chinese looks like 安定门） was built when the gate called Anzhenmen was moved south during the early Ming dynasty. It is located on the western side of the inner city’s northern wall. The name signifies that the wall was built for sacred purposes or as way of signifying peace under the gods, as the term Andingmen literally means "peace and tranquility under the heavens." Its gate tower’s measurements are 31 meters by 16.5 meters and 36 meters in height. The barbican is 68 meters by 62 meters, with a sluice gate and an archway on its western side. The barbican was dismantled in 1915 and the gate tower and watchtower in 1969.

Seven of Beijing's Inner City Gates had a Guandi Temple built within their grounds. However, Andingmen and Deshengmen had Zhenwu Temples built instead. These gates were used by soldiers entering and leaving the city.

Andingmen was informally known as "生门 Shengmen." Shengmen is a name that when translated to English means "bountiful harvest."

The Emperor was known to frequently use this gate when leaving the city. At the Temple of Earth, he would pray for a bountiful harvest. The wall still stands there as does the legacy of Andingmen in the history city of Beijing, China.
