Xi'an is a city famous for its history, and its city wall is a robust testament to that. The 14 kilometer city wall was first completed in 190 BC, encircling a 14 square kilometer section of the city. It stands today, wonderfully preserved, a must see destination for the city's visitors.
On sunny clear days, the wall offers some wonderful views of the city and its landmarks. And on a drizzly day, you can envision the melancholic past where lonesome troops minded their lookouts.
