Tailor worked in part of Venice (6)
I believe the answer is:
rialto
'part of venice' is the definition.
'tailor worked' is the wordplay.
'worked' is an anagram indicator.
'tailor' anagrammed gives 'RIALTO'.
'in' is the link.
(Other definitions for rialto that I've seen before include "Island in Venice with famous bridge" , "exchange" , "business centre" , "famous city district" , "Area famous for 7 [ABRIDGE]" .)
