Guanches

Coasttocoast has this photo of a pyramid in the Canary Islands and mentions the Guanches.

They could be Atlanteans.

It reminds me of this Randy Newman lyric:

Great Nations of Europe

The Grand Canary Islands
First land to which they came
They slaughtered all the canaries
Which gave the land its name
There were natives there called Guanches
Guanches by the score
Bullets, disease, the Portugese, and they weren't there anymore
Now they're gone, they're gone, they're really gone
You've never seen anyone so gone
They're a picture in a museum
Some lines written in a book
But you won't find a live one no matter where you look

Hide your wives and daughters
Hide the groceries too
Great nations of Europe coming through
