At the Juyongguan Pass of the Great Wall of China in Beijing

It's amazing how much we didn't know about the places we visited in China. For example, I didn't know the name of the entrance of this part of the Great Wall. Just comparing my pictures with those on the Internet, I conclude we went to the Juyongguan Pass of the Great Wall of China. It's near the Badaling entrance except this part of the wall goes over a major freeway.

This is the Northern Gate of the Juyongguan Pass.
