I went to see this during an overnight trip to Baotou while vacationing in Hohhot. Other than the rock sign saying what the place was, and the Mongol on a horse on a hill, there was nothing indicating exactly what spot was the ruins of the wall. So, I'm not sure what it was I was supposed to see.

Considering the ruin of the Great Wall makes one consider the politics surrounding it, and of its renovations and maintenance in other locations. If you're out this way, it's a good stop, but probably not worth the trip unless you are a scientist or historian. It was equally intriguing to see the wall at nearby sites, where it was little more than a crumbled strip of gravel and chips running off into the distances at about 1 foot high by 4 feet wide.
