During the past days, in the prehistoric Underground Labyrinth Ravne the complete wooden support has been replaced in the chamber number 3. The replacement took ten days and instead of the existing supports and timbers, the new ones thermally processed and the new planks are installed.
In this way, the hard working team of the “Archaeological Park: Bosnian Pyramid of the Sun” Foundation continues with the high level security maintenance in the tunnels Ravne. The replacement of the wooden support continues with the plan that by May 2017 the tunnels will have all wooden supports not older than two years.
