Located five miles northeast of Shanhaiguan Pass, Sandaoguan
Great Wall (meaning "Three Passes Great Wall") was built to defend
against enemy intrusions in the ancient wars. The wall was strategically
important and gives the appearance of a giant dragon surging forward
to the top of the cliffs and then suddenly rushing down to the
bottom of the valley.
The wall was built by layering stones. It is over fifteen feet
high, 6.5 feet wide and over 500 yards long. The first pass is
a gully surrounded by steep cliffs; the second lies between two
precipices standing face-to-face and the third pass is located
high on the mountain.
It is no exaggeration to say Sandaoguan Great Wall is one of
the most wondrous segments of the Great Wall. Amazingly, some
segments of the wall here were built on cliffs at a 90 degree
incline. It appropriately earned the nickname "The Wall Hanging
Upside Down."
