During the winter of 2018 and spring 2019, the Foundation ‘Archeological Park: Bosnian Pyramid of the Sun’ will dispose three teams on cleaning the Underground tunnel complex Ravne.
The first team works in the Underground Labyrinth of Ravne, moving southward in the direction of the Bosnian Pyramid of the Sun. The second team cleans the tunnels ‘Ravne 3’. The third team is working on a new ‘Healing Tunnel’ located under the Healing Forest.
After fifteen meters in the Healing Tunnel, the first round sandstone block was found, and in the continuation a somewhat larger uneven block on the floor. The direction of the tunnel is towards the south and the Bosnian Pyramid of the Sun.
Electric cables are installed so that workers can work under the illumination.
