Wigtown Harbour or Wigtown Quay was relocated in 1818 to serve the town of Wigtown and its hinterland in Wigtownshire, Dumfries and Galloway, following the silting up of the original natural harbour that was once located near to St Machute's church (NX 43673 55707). This relocation occurred following centuries of silting and then the alteration of the course of the River Bladnoch that runs into Wigtown Bay where it joins the River Cree.
