Catholic treasures moved in underground tunnels hundreds of years ago in Puebla, Mexico
An article from the newspaper El Pais describes these underground tunnels built from the 1500s on : “How a Mexican city discovered its long-forgotten ancient tunnels. For decades the secret passageways in Puebla were nothing more than a rumor”
The tunnels were also used by Mexican soldiers in battles against the French.
