The Mongolian Yurt, called "a vaulted tent" or "felt tent" in ancient times, is a domed pealed tent. The frame of the yurt is a supporting ring, formed by some wooden poles. The yurt's frame is covered with thick felt fastened from outside with ropes. Every yurt has an opening on the top, which provides both light and ventilation, and a wooden door facing south or southeast. The convenient design suits the mobility of the Mongolian people who live on grazing. As more and more Mongolians settle down, yurts are decreasing in number. [Photo/CFP]
