One of the oldest and largest pyramids in the world is found in Tibet - the White Pyramid,
located in the Qin Ling Shan mountains, about100 km southwest of the city of Xi'an,
 in the People's Republic of China.  It is reported to be about 300 meters high.   

Life Magazine had a picture of this Tibetan Pyramid taken in 1957. The first picture to be seen here was taken from a C-54 in world war II by a pilot who flew supplies through the Himalaya Mountain terran as a volunteer helping the Chinese.
Hartwig Hausdorf, a researcher in Germany, sent over photographs from his collection, taken during his 1994 trip to the Forbidden Zone in The Shensi Province in China.
Estimates for an age are 4,500 years old. Hausdorf mentions the diaries of two Australian traders who, in 1912, met an old Buddhist monk who told them these pyramids are mentioned in the 5,000 year old records of his monastery as being "very old."
Hausdorf reports: There are over 100 pyramids, made of clay, that have become nearly stone hard over the centuries. Many are damaged by erosion or farming. One pyramid is as large as the Pyramid of the Sun of Teotihuacan in Mexico (which is as large as the Great Pyramid of Giza). Most are flat topped, some have small temples on top. There is a stone pyramid in Shandong, about 50 feet tall. Some incorporate the golden proportion. These images were taken by Hartwig Hausdorf, a researcher in Germany.
