I have been to both of these sites ~ Leptus Magna and Sabratha~ as a teenager.
They are absolutely spectacular.
The sunken ruins off shore in the Mediterranean are well known to scuba divers and snorklers.
None of this is of importance to the Libyans, however, since it is not Arab.
I was also priviledged to have gone to a newly excavated Christian Church, dating to the early centuries of the First Millenium, right in Tripoli.
I had to climb down a ladder about ten feet, and entered an area with a baptistry and altar.
It was a truly moving experience to be where early Christians had worshipped.
Thanks happygrl!
