Rush to see the ruins of Athens (6)
I believe the answer is:
hasten
'rush' is the definition.
(I know that rush can be written as hasten)
'the ruins of athens' is the wordplay.
'the ruins of' indicates anagramming the letters.
'athens' anagrammed gives 'HASTEN'.
'to see' acts as a link.
(Other definitions for hasten that I've seen before include "Speed up" , "Act or move fast" , "Travel with expedition" , "Athens (anag.)" , "Be quick to do something" .)
