It's seen in Egypt as dawn breaks before morning (5,3)
I believe the answer is:
aswan dam
'it's seen in egypt' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'as dawn breaks before morning' is the wordplay.
'breaks' indicates an anagram.
'before' says to put letters next to each other.
'morning' becomes 'am'.
'dawn' with letters rearranged gives 'wand'.
'as'+'wand'+'am'='ASWAN DAM'
Can you help me to learn more?
(Other definitions for aswan dam that I've seen before include "Egypt's lake district" , "massive barrier" , "Nile construction of 1902" , "Huge structure in Africa" , "Egyptian water barrier" .)
