Like a lot of cathedrals and mosques? Tour southern Europe and North Africa, perhaps (5)
I believe the answer is:
domed
'cathedrals and mosques? tour southern europe and north africa perhaps' is the definition.
I can't tell whether this defines the answer.
'like a lot' is the wordplay.
'like' becomes 'dome' (I can't explain this - if you can you should give a lot more credence to this answer).
'a lot' becomes 'd'.
'dome'+'d'='DOMED'
'of' is the link.
Can you help me to learn more?
(Other definitions for domed that I've seen before include "Vaulted" , "cupola" , "with a meniscus" , "Shaped like rounded roof" , "not flat!" .)
