the parthenon

I'm a little stuck... Click here to teach me more about this clue!

'greek classic' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'penn hero that remodelled' is the wordplay.
'remodelled' indicates anagramming the letters.
'penn'+'hero'+'that'='pennherothat'
'pennherothat' is an anagram of 'THE PARTHENON'.

'this' is the link.

Can you help me to learn more?
