Bosnian Pyramid discoverer Dr Sam Osmanagich explains amazing astronomical aspect of the Bosnian Pyramids during the Summer Solstice day, June 21st. Shadow of the Bosnian Pyramid of the Sun touches bottom of the southwest corner (foundation) of the Bosnian Pyramid of the Moon. Height of the shadow equals height of the Bosnian Pyramid of the Moon (190 m) observed from the top of the Bosnian Pyramid of the Sun. On the other hand, shadow of the Bosnian Pyramid of Love completely covers Temple of the Mother Earth. Another undeniable proof that top of the Bosnian Pyramid of the Sun had been used as oldest astronomical observatory!
