Summer 2020 excavations being conducted at the Ravne Tunnels Complex within the Bosnian Valley of the Pyramids will be primarily focused on two key localities; Ravne 3 and Ravne 4. These two sections of tunnels represent the most recently developed and active archaeological sites within the complex.The Ravne Tunnels Complex is a prehistoric system of subterranean passages and chambers that at some point in the past have been almost entirely blocked up with loose rubble. Work has been ongoing since the discovery of the tunnels in 2006 to remove this material so that they may be explored. The principle purpose of the excavations is to identify a route through the ancient tunnels to gain subterranean access to the nearby Bosnian Pyramid of the Sun.
