I didn't know this. Amazing.
The largest and oldest pyramid ever discovered is in South America. The base of this SA pyramid is 7 times larger than the largest in Egypt. Keep your eyes on South America for some very suprising discoveries in the near future.
2.6 times longer and 2.6 times wider. Is it higher?
What about this one?
A STRUCTURE thought to be the world's oldest building, nearly twice the age of the great pyramids of Egypt, has been discovered. The rectangular stone ziggurat under the sea off the coast of Japan could be the first evidence of a previously unknown Stone Age civilisation, say archeologists.
The monument is 600ft wide and 90ft high and has been dated to at least 8000BC. The oldest pyramid in Egypt, the Step Pyramid at Saqqara, was constructed more than 5,000 years later.
