The Bosnian Pyramid of the Sun is the largest pyramid in the world, with a height of over 220 meters. It has a regular pyramid geometry with three well-preserved sides: north, east, and west. The pyramid is covered with concrete blocks that, according to analyses by Bosnian and Italian material institutes, have high compressive strength and low water absorption, making them superior to modern concretes. German geophysicists’ ground-penetrating radar scans in 2007. confirmed the existence of internal passageways in the pyramid. Croatian physicists (in 2010) detected the existence of an energy beam with a radius of 4.5 meters passing through the top of the pyramid, while Italian and Finnish experts (in 2011) recorded the phenomenon of ultrasound at the top of the pyramid. During the summer months, the shadow of the Bosnian Pyramid of the Sun covers the Bosnian Pyramid of the Moon just before sunset, showing a clear astronomical relationship between these two pyramids. The pyramid is covered with layers of soil and vegetation similar to hundreds of pyramids in China, Mexico, or Guatemala. The Federal Institute of Pedology estimated the age of the earth’s cover to be 12,000 years, making the Bosnian Pyramid of the Sun the oldest pyramid on the planet.
