Famous Venetian bridge (6)
I believe the answer is:
rialto
'famous venetian bridge' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for rialto that I've seen before include "Famous Venetian bridge" , "famous city district" , "Bridge in Venice and Dublin" , "Island in Venice with famous bridge" , "Area famous for 7 [ABRIDGE]" .)
