War of 1812 treaty site (5)
I believe the answer is:
ghent
'war of 1812 treaty site' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ghent that I've seen before include "Belgian city (from which the "good news" was brought to Aix)" , "Flanders city/port" , "Belgian port" , "NW Belgian city" , "source of good news" .)
