A plan has been put forth to build the world's largest structure in Dessau, Germany-- a new Great Pyramid that would be ten times larger than the one in Egypt. Estimated to take 30 years to construct, the huge building would serve as a communal tomb, open to all, regardless of denomination or nationality. For more on the project, visit CNET News(1).
