Criticise article about memorial building (8)
I believe the answer is:
pantheon
'memorial building' is the definition.
(Paris landmark)
'criticise article about' is the wordplay.
'criticise' becomes 'pan' (informal term meaning to criticise heavily).
'article' becomes 'the' (the 'definite article' part of speech).
'about' becomes 'on' (**).
'pan'+'the'+'on'='PANTHEON'
(Other definitions for pantheon that I've seen before include "Roman building" , "All the gods of a people or religion" , "Circular temple in Rome" , "Ancient Roman temple" , "Group of greats" .)
