Sinai Peninsula; Egypt
Around Mount Moses and Mount Katarina in the centre of Sinai
peninsula can be found some (nine by bibliography) complexes
with small, corbelled objects, named nawamis.
The findings in the objects (human bones) tells us about the
use: those were the tombs. Radiocarbon investigations, made
with both bones and stones, tell us about the age: 4000 years.
But construction can not be so old without regular maintaining,
and this age is not so real for the shelters themselves.
Inner part is typical corbelling, outside there is oval built
walls, more or less vertical until the gravelled roof. Nowadays
roof is more or less concave: but gravel disappeared in time
and it is not original shape.
