              I think the title can be deceiving. The tunnel system Albarradón de Ecatepec was built by the European invaders, but the paintings found in the tunnels were painted by natives worked in the construction of the tunnels.

                      if you read the linked article, it says an Iranian company called Kayson builds tunnels at far places like Venezuela, Belarus, Cameroon, India. Can this be true?

                        This is nonsense. Italian companies do a lot of great work in Italy and abroad. But if the corrupt government does not want to spend money for the maintenance of the tunnels or assigns too little money, then you get what you pay for.
