Xi'an City Wall(Xi'an Ancient City Wall)

Xi'an City Wall, also known as the Xi'an Ming City Wall, is an ancient city wall defense system encircling the old city of Xi'an from the Ming and Qing dynasties. The main body of the existing wall was built during the Hongwu period of the Ming Dynasty, expanded on the foundation of the imperial city of Chang'an from the Sui and Tang dynasties, and has undergone multiple renovations since then, remaining well preserved to this day. The wall is roughly rectangular in plan, with a perimeter of about 14 km, and the area it encloses is the old city of Xi'an. The wall is about 12 m high, about 15 to 18 m wide at the base, and about 12 to 14 m wide at the top. The top of the wall is broad and flat, allowing visitors to cycle or stroll along it while overlooking the scenery inside and outside the city. The defensive system of the wall consists of the wall body, city gates, barbicans, bastions, corner towers, and the moat. Nearly a hundred bastions were built along the outer face of the wall, spaced about 120 m apart, precisely within bow-and-arrow range, reflecting the defensive wisdom of the cold weapon era. There is a corner platform at each of the four corners, among which the southwest corner platform is circular, forming a striking contrast with the other three square corner platforms—a unique form rarely seen among surviving ancient city walls. The moat outside the wall encircles the entire city, together with the wall forming a complete defensive layout. The wall currently has 18 city gates, among which Yongning Gate (South Gate), Anding Gate (West Gate), Anyuan Gate (North Gate), and Changle Gate (East Gate) are the four main gates originally built in the Ming Dynasty. Each main gate features three tiers of gate towers—the gate control tower, arrow tower, and main tower—forming a layered barbican defense. Yongning Gate is the one that has been in use the longest, with a history dating back to the Sui Dynasty, and is also the one whose form is relatively well preserved. The section of the wall at Hanguang Gate encloses the remains of the Sui and Tang imperial city, with a site exhibition that offers an intuitive sense of the wall's layered history spanning over a thousand years. Cycling a full loop around the city on the wall is a popular experience, taking about one and a half to two hours in total. Ascending the wall in the evening allows you to take in both the traditional architecture inside the city and the modern urban skyline outside, with the wall and moat set off beautifully against the glow of the setting sun.
