The section of Ming-era city wall in this area was constructed in the fourth year of the Zhengtong reign (1439) and formed part of Beijing's Inner City wall. The central portion retains the junction where it connected with the Outer City wall, while the southern section consists of the surviving rampart base of the Inner City's Southwest Corner Tower. To the west of this segment of the Inner City wall once stood Xibianmen—one of the seven gates of the Outer City—as well as an Outer City water gate; however, neither remains today.
