This paper takes the constitutional and distribution features of the surrounding exterior space of the city gate of Chongqing in the late Qing Dynasty as the research focus. It analyzes and studies the constituting and structuring forms of the gates, wharfs, temples, and bridges. In addition, the inhabitants’ occupations and the arrangement forms of inhabitant buildings were examined. This research has revealed the following human purposes of the various spaces. The open-gate space was the gathering and dispersing center of the flow of humans and goods. The closed-gate space was the gathering place for religious and cultural activities. The Converging Zone was the space predominantly used for political functions. The Yangtze River Zone was the space that served primarily commercial functions. The Land Zone was the space for religious functions. The Jialing River Zone was the space for transportation and agriculture. The constituting features of the surrounding exterior space of the city gate reflected the idea of “the Golden Mean,” and the implications of the “Four Gods” influenced the function distribution of the surrounding exterior space of the city gate.
