Stop 6: Heping Gate
To find the most complete gate along the Ming City Wall, you'll need to walk along Xuanwu Lake til you reach the northernmost point of the old Nanjing City, which forms a straight north-south axis with Zhonghua Gate on the southern boundary.
Located just to the north of Xuanwu Lake, the fortress, also known as Shence Gate, was a guarded military zone inaccessible to the public for more than seven decades, according to Sun.
As a result, Heping or Peace Gate is the only gate of 13 along the Ming City Wall to have a watchtower that predates 1912, the founding of the Republic of China.
The gate was repurposed as a public park in 2006.
The 1,600-meter stretch of wall between Xuanwu Gate and Shence Gate is a key section of the government's plan to open more of the wall to the public this year.
