The Ancient City Wall at in Xi'an is one of the best-preserved city walls in China. It was built in the 14th century during the Ming Dynasty, under the regime of Emperor Zhu Yuanzhang, and expanded upon from walls remaining from the Tang Dynasty. Visitors can either cycle or walk along the Ancient City Wall, which is almost 14 kilometers long and takes around three hours at a leisurely pace. The site features a moat, a drawbridge, the main towers, watchtowers, and gates, all of which combine to depict an impressive ancient defense system.
The South Gate is situated near the Bell Tower and is widely considered to be the most significant, with greeting ceremonies by the government held in the South Gate Square, which has recently been restored. Like the other gates, the South Gate features three towers – the gate tower, which holds the drawbridge, the narrow tower and the main tower.
