In 2005 a hill named Visočica, in Bosnia, caught the attention of the world due to its striking resemblance to pyramids of Central America (prior to excavation). Many in the scientific community were quick to scoff at this theory and claimed the so-called pyramid of the sun, as well as other similar formations nearby, as being natural and not man-made, while others marvelled at the site claiming that a structure underneath the soil might date back as much as 48,000 years (a fact that could change history as we know it).
Bosnian Author Semir Osmanagić, (a self-styled "Indiana Jones" of the Balkans) with the help of an international team of archaeologists claims to have found a paved path and a tunnel as well as numerous stone carved blocks. There is also talk about a strange ceramic statuettes found underneath the pyramids (though no online pictures could be found).
Recent findings from July 2011 show signs of some kind of peculiar tomb inside one of the tunnels while using a new and sophisticated kind of geo-radar. Google translation from the website called www.antikitera.net describes the site as: "The found structure could be a composed interment from two bodies located to different depths: first to 1.5 meters of depth and the second to 3 meters. Two overlapping rooms entirely in stone with a morphology similar to two rhombus, to their inside the tracing of the geo-radar show of the white areas correspondents to air. The presence of two remains suspended in the middle can be presumed. The dimensions of the interments turn out to be those canonical ones of 1 x 2 meters approximately. The depth of the entire complex arrives to approximately 4.3 meters. The diggings are begun 25th July and are still on course."
There isn't enough proof to actually make this site a valid archaeological find. Should this one day be proven otherwise, it would mean that the Bosnian pyramid of the sun would be one third bigger than the great pyramid of Giza, making it the biggest pyramid in the world as well as the oldest on the planet.
