Just 125 miles from the Texas border.
This vast archaeological site
situated near the base
of the Sierra Madre Occidental mountain range
dates back to 1200 AD.
Known as both Paquimé and Casas Grandes,
only part of the extensive remains
estimated to contain more than 2,000 clay rooms
have been excavated,
revealing a well-planned city containing plazas, stores,
workshops and multi-story residential buildings.
With an advanced water and sewage system.
Paquimé, or Casas Grandes,
is larger than any other site
for hundreds of miles in any direction.
And there's an interesting melding of different cultures.
In some aspects, it's a very Mesoamerican, or Aztec city.
In other regards,
it's a very Pueblo or Southwest culture city.
[narrator]
is believed to have had a population
of more than 10,000.
But this thriving pre-Columbian civilization
declined and mysteriously disappeared
by the 16th century.
While no one knows exactly
who the inhabitants of Paquimé were,
It is believed that their descendants may be
the indigenous people of the region known
as the Tarahumara.
The Tarahumara now live high up
in the canyons of the Sierra Madre.
And much of what is known about the ancient city of Paquimé
comes from the stories passed down to them
from their ancestors.
According to their legends,
Paquimé is a sacred place
where star people have appeared for centuries.
Described as light, tall and blonde,
the Tarahumara say these mysterious beings
emerged from doorways in the ruins.
[Hawkes]
exist still today, in the Chihuahuan Desert.
They believe that these tall, blonde people
represent maybe the heirs of the star people
that first brought them to this world.
They believe that there is a portal
and that these start people use this portal today
to transport to various places on the Earth
and off-world as well.
[narrator]
are hundreds of uniquely T-shaped openings.
Openings that closely resemble an ancient doorway
more than 4,000 miles away in southern Peru.
Here, perched high in the Andes mountains,
this shallow T-shaped opening
called the doorway of Amaru Muru
is surrounded by many legends describing it
as an active portal
that transports beings both into and out of this world.
This could be a coincidence
if it weren't for the fact that at Paquimé
there are strange stories of the appearance
of these Caucasian-like beings.
And there are very similar stories to do with this gate
of the gods in Peru.
It's possible that this does represent
a Stargate location
in which extraterrestrial humans
are seen as coming and going.
During certain opportune points in the year
when the Stargate becomes active.
[narrator]
and legends of otherworldly beings
at Paquimé and Amaru Muru,
is it possible that extraterrestrials
once accessed these ancient sites through Stargates?
Some ancient astronaut theorists
say that not only were Stargates present
at places like Paquimé and Amaru Muru
in the distant past,
but that there may be functioning Stargates
here on Earth even today.
