A series of wonderful Reuters photos show Chinese children studying and playing in a school campus built in a cave.
A general view shows the Dongzhong (literally meaning "in cave") primary school at a Miao village in Ziyun county, southwest China's Guizhou province, November 14, 2007. The school is built in a huge, aircraft hanger-sized natural cave, carved out of a mountain over thousands of years by wind, water and seismic shifts.Link (Thanks, Rick!)
