Times article on centre of Padua, an idyllic place (6)
I believe the answer is:
xanadu
'an idyllic place' is the definition.
(I've seen this before)
'times article on centre of padua' is the wordplay.
'times' becomes 'x' (2 times 4 is 2 x 4).
'article' becomes 'an' (indefinite article).
'on' is a charade indicator (letters next to each other).
'centre of' says to take the centre.
The middle letters of 'padua' are 'adu'.
'x'+'an'+'adu'='XANADU'
(Other definitions for xanadu that I've seen before include "Idealised place of great luxury" , "Idyllic location" , "'In . . . . . . did Kubla Khan / a stately pleasure-dome decree' (Coleridge)" , "Kubla Khan's place (Coleridge)" , "ideal place" .)
