The great Tartar wall in China

Just wanted to share these few images and see what you think about this Chinese Tartar wall. I have never heard of it. Have you? They call it: Beijing city fortifications.

• The Inner city wall was 24 kilometres (15 mi) long and 15 metres (49 ft) high, with a thickness of 20 metres (66 ft) at ground level and 12 metres (39 ft) at the top, and had nine gates.
• The wall stood for nearly 530 years, but in 1965, was removed to allow for construction of the 2nd Ring Road and Line 2 of the Beijing Subway.
• Only one part of the original wall still exists, just south of the Beijing railway station in the southeast portion of the city.
• The Outer city walls had a perimeter of approximately 28 kilometres (17 mi).
• The entire enclosure of the Inner and Outer cities formed a shape with a perimeter of nearly 60 kilometres (37 mi).

KD: Figured it was an important piece of architecture to be familiar with. Additionally, it definitely has a familiar name...
