Xi'an

Xi’an was once the start of the indispensable Silk Road that made commerce between many countries in Eurasia possible. It was also the imperial seat for no fewer than eleven dynasties, before the unification of China between 1000 BC and 1000 AD making it one of the Four Great Ancient Capitals of China. Its most famous attractions is the rather recently discovered Terracotta Army, the protectors of the tomb of the first emperor of China. Xi’an also boast 14th century city walls that are more than 12 km (8 miles) long. They are not only a part of the city history, but traveling in Xi’an sometimes requires going under, on or around them.
