Terra Cotta:
The Terra Cotta Warriors and Horses are the most significant archeological excavations of the 20th century. Work is ongoing at this site, which is around 1.5 kilometers east of Emperor Qin Shi Huang's Mausoleum, Lintong County, Shaanxi province. It is a sight not to be missed by any visitor to China.
Upon ascending the throne at the age of 13 (in 246 BC), Qin Shi Huang, later the first Emperor of all China, had work begun on his mausoleum. It took 11 years to finish. It is speculated that many buried treasures and sacrificial objects had accompanied the emperor in his after life. A group of peasants uncovered some pottery while digging for a well nearby the royal tomb in 1974. Life size terracotta figures of warriors and horses arranged in battle formations are the star features at the museum. They are replicas of what the imperial guard should look like in those days of pomp and vigor.
Big Wild Goose Pagoda:
The Big Goose Pagoda is situated in the Da Ci'en Temple. It is one of the city's most distinctive and outstanding landmarks, possibly the most beautiful building left in Xian today.
Known as the best-preserved Buddhist temple complex, the Da Ci'en Temple was initially built in 589, during the Sui Dynasty (581-618). Within the temple, there is a small bell tower from which a bell, which was used for telling time to the monks in ancient times, hangs. Daxiongbaodian is the main hall of the temple.
City Wall:
When Zhu Yuanzhang, the first Emperor of the Ming dynasty (1368-1644), captured Huizhou, a hermit named Zhu Sheng admonished him that he should "built high walls, store abundant food supplies and take time to be an Emperor," so that he could fortify the city and unify the other states. After the establishment of the Ming dynasty, Zhu Yuanzhang followed his advice and began to enlarge the wall built initially during the old Tang dynasty (618 -907), creating the modern Xian City Wall. It's the most complete city wall that has survived in China, as well being one of the largest ancient military defensive systems in the world.
After the extension, the wall now stands 12 meters (40 feet) tall, 12-14 meters (40-46 feet) wide at the top and 15-18 meters (50-60 feet) thick at the bottom. It covers 13.7 kilometers (8.5 miles) in length with a deep moat surrounding it.
