The world's largest city wall, it has been restored and is 12 m high, 18 m wide at the bottom, 15m wide on the top, and 13.7 km long. Bikes (including two- or three-person models) can be rented for ¥40 per 120 minutes/bike (or ¥80 for a tandem) plus a ¥200 deposit. You can hire one at the top of the South or East gate; you may return it to other stations on the wall (there is one at each of the four main gates), but be sure to verify this before starting your ride, and remember that most gates close at 18:00 or 19:00 and the Zhongshan Gate shuts at 21:00. Only the south gate is open till 23:00. Bikes will not be rented if there is any chance of rain, because the top of the wall becomes slippery. Check the weather forecast before you buy a ticket to enter the wall. If you want to foot it though, a complete loop of the walls takes 4-5 hours. The landscaped park around the base of the exterior walls and moat also makes for a pleasant stroll and gives a different perspective on the battlements and towers. The wall is lit up at night and makes for a pleasant stroll. The present city wall was built in the Ming dynasty (AD 1368-1644) on the foundation of the Chang'an Imperial city wall of Tang dynasty (AD 618-907). The Xi'an City Wall International Marathon is held each year in November since 1993, with athletes from more than 50 countries running on top of the wall. Also, the Xi'an city wall Cycling Race is held on top of the wall since two years ago. There is a small museum inside the city wall at Hanguang Gate, about halfway between the southwest corner and the South Gate, accessible from the top of the wall. Look for a staircase down inside a covered structure. Inside are the unrestored remains of a gatehouse and a calligraphy collection.
The fortifications of Xi'an in Shaanxi, also known as the Xi'an City Wall, represent one of the oldest, largest, and best preserved Chinese city walls. It was built under the rule of the Hongwu Emperor of the Ming dynasty to protect the city from the Northern Yuan and potential unrest. It exhibits the "complete features of the rampart architecture of feudal society". It has been refurbished many times since it was first built in the 14th century with the most important three reconstructions occurring in the late 1500s, in the late 1700s, and in 1983. The wall encloses an area of about 11.52 square kilometres (4.45 mi2).

Walk along the city walls and see the South Gate (南门 Nánmén, literally translated as "The Southern Gate"), which is illuminated at night. The area outside of the "Gate" is full of big shopping malls that are popular among the locals, marked with the iconic glass-curtain walled buildings. The area is one of the busiest places of interests in the city.
西安碑林博物馆; Xī'ān Bēilín Bówùguǎn
Remarkable collection of 4000 inscribed stone tablets, covering scripture, poetry, classic Chinese texts, triumphs of rulers, family history, and practical affairs such as instructions to rebuild a school. The 7th century Nestorian Stele (Showroom 2, first exhibit on the left) depicts the coming of Nestorian Christianity to China.
卧龙寺
This active Buddhist temple dates back to 200 BC. It has been restored, and is vibrant and busy.
钟楼; Zhōnglóu
The traffic island is almost ringed by a subway, enter from north side next to Metro entrance. Great tower with ancient bells to toll the time for the city. Short musical performances every hour or so.
Huimin Street (回民街 Huímínjiē)
Walk through the Muslim quarter sampling food and buying souvenirs. The Hui Muslim Quarter (回民街 Huí mín jiē, hwei-min-jyeh) is a series of small alleys located in a high-density Hui community (very much like Chinatown in North America) inside the city walls, where the residences open up small restaurants and food shops like street food. Some of these restaurants are among the most famous ones in the city, regarded as the "true Xi'an cuisine" by the locals. However, visitors from outside the city may dislike the environment while the locals may not, because garbage can be seen almost everywhere on the street. Price is high here (some time more doubled) without matching the quality. It is recommended to try only the Huimin food here while keeping other Xi'an delicacies elsewhere in the city.
鼓楼; Gǔlóu
Great tower with drums to toll the time to the old city. Short musical performances every hour or so.
