Seventeen lost pyramids are among the buildings identified in a new satellite survey of Egypt.
More than 1,000 tombs and 3,000 ancient settlements were also revealed
by looking at infra-red images which show up underground buildings.
Initial excavations have already confirmed some of the findings,
including two suspected pyramids.
The work has been pioneered at the University of Alabama at Birmingham by US Egyptologist Dr Sarah Parcak.
She says she was amazed at how much she and her team has found.
“We were very intensely doing this research for over a year.
I could see the data as it was emerging,
but for me the “Aha!” moment was
when I could step back and look at everything that we’d found
and I couldn’t believe we could locate so many sites all over Egypt.
