This year, just like many previous, volunteers will give great contribution to the investigation of the Bosnian pyramids. Volunteering will take place in two ways: (1) participants of eleven days program "Expeditions to the Bosnian Pyramids with volunteering" will spend four days working on the sites, and (2) to all others volunteers will be given a chance to work in the days provided for volunteers.

"Archaeological Park: Bosnian Pyramid of the Sun" published a calendar of volunteering with a total of 40 terms/days in the season 2015. The work will take place at three locations: The Underground labyrinth Ravne, Bosnian Pyramid of the Sun and Bosnian Pyramid of the Moon.

On June 2, participants of the first group of "Expedition to the Bosnian Pyramids" came in Visoko, on June 4 they already had first working day inside and in front of the tunnel Ravne. One group of volunteers was taking out pebbles from closed tunnels, another group was working on the control of material in a search for artifacts, tools and organic material.

The head of the expert team of Foundation were an archaeologist Anela Preljevic and geologist Meira Kozlo.

The first working day started at 9:00 AM and finished at 3:00 PM. Job has been successfully done, and all volunteers felt as a part of the team on this project of global importance.
