'Huge underground structures found beneath Giza pyramids spark conspiracy theories about ancient power grid': Archaeologists have discovered mysterious underground structures 600 metres below the pyramids.

It includes eight vertical cylindrical wells 648 m deep, which connect two huge "cubic chambers". The mysterious discovery adds fuel to decades of theories that the pyramids could be more than what they seem.
