Today, we visited the Longmen Caves. Out of the walls of these caves (and the surrounding cliffs), more than one hundred thousand (!) Buddha statues have been carved in the time of the Northern Wei dynasty (some 1,300 to 1,500 years ago).
Update from October 31, 2016Additional pictures are available.
This huge number alone is already quite impressive. Most impressive, though, are the largest statues (which are several metres in height) with their flanking bodhisattvas.
