During the Day of the Dead celebrations this year, I was in Mexico City for a couple of events.

And like I do in many places that I visited, I started looking for stories.

And yes, there were typical ones about the dark streets of the city, stories of ghosts and the streets.

But none were as creepy as the underground stories.

Quite literally underground.

And let me tell you, Mexico City has a strange relationship with the ground it's built on.

It was a Spanish that built what we know now as Mexico City over the ruins of the

Aztec capital of Tenochteland back in the 1500s.

The city itself is built on layers upon layers of sand and clay,

some up to 100 yards deep, that used to be a lake.

Important areas like the Great Temple or Templo Major,

which was discovered in 1978, is also there.

But there are also some more recent findings. Archaeologists have found skulls, traces of the old city literally underground.

Obviously, this is an enormous topic, but today I'd like to tell you about today's strange stories

with some of the legends of those that

nowadays live and travel through that city on a daily basis.

Legends and strange encounters in the tunnels underground, where there's trains and shops and

guards.

And I also want to tell you about things that those who walk on the surface may never become aware of,

that they're walking above a city of ghosts.

My name is Edwin, and here is a dark man.

The crowds were large, with about a month before the huge celebration in the city remembering when the country declared its independence. Mexico City was already a huge metropolitan area, with buses and underground metro stations connecting everybody even closer than they already were.
