En 1912 hallaron túneles en Buenos Aires que no debían existir

In 1912, workers on the first Buenos Aires subway discovered colonial masonry galleries beneath Avenida de Mayo. The Siemens-Schuckert technical report described them as being of superior construction to what they themselves were using. They did not appear on any known municipal map. The report recommended investigating them before demolishing them. There is no record that this investigation ever took place. The subway was inaugurated in 1913. The report has been in the Historical Archive of the City of Buenos Aires since 1912. In Mexico City, INAH reports document unmapped colonial infrastructure found during the construction of the Metro in 1967. Same city, same pattern. The documents have always existed. #BuriedInfrastructure #Declassified #BuenosAires #SubteBA #HiddenHistory #CDMX #Metro #UrbanArchaeology #LatinHistory #SecretDocuments ⚠️ LEGAL NOTICE: All content—research, narration, scripts, and images—is original work by Desclasificado and protected by copyright.
