Vratnica - Prehistoric Temple?
Unusual burial or temple construction located in the village of Gornja Vratnica 4 km from the Bosnian pyramid of the Sun. In fact that “vratnica” in Bosnian is “gate”. Local people call this site Toprakalia. The view of this construction looks like two massive burial mounds connected with each other. A researcher from Austria Gabriela Lukacs considers that Vratnica is an ancient burial complex of the pyramid builders of Visoko valley.
In the end of 2006, a team of researchers from Germany and Serbia used geo-radar for screening Toprakalia. They noticed some features of possible stairs, rooms and underground passages inside the construction.
The excavation began in 2007, several layers of stone plates were found there, one of them is very massive with waved surface.
