The Chinkana is an Inca tunnel network beneath Sacsayhuamán. A 2025 report measured more than 1,750 metres of passages at depths of up to 2.5 metres. Available sources do not establish that the tunnels extend toward Corona, are completely dark throughout, or were constructed without artificial light. The claim that they were carved directly from bedrock is also unsupported.
