WebEcoist has an article on 15 amazing earthen buildings from around the world. From the old to the modern, from small and inconspicuous to large and impressive, these buildings made of earth are worth a look. Although this list omits the mud skyscrapers of Yemen, it includes the equally stunning Hakka houses of China, and the fired ceramic ‘Geltaftan’ buildings where the building itself becomes the firing kiln, making it highly earthquake resistant.
