In the Valley of the Bosnian Pyramids in the town of Visoko, closest to the Pyramid of the Moon, a Tumulus has been found in the village of Vratnica.
A tumulus is a mound of earth, usually placed over a prehistoric tomb. The Tumulus of Vratnica is a 32 meter high manmade hill, discovered in 2008. An exposed clay-and-concrete megalithic block was found, which was discolored due to its contact with the elements. Soon after this discovery, more blocks were found, which lead to what appeared to be a huge megalithic terrace and possibly a gateway to the Bosnian Pyramids.
