The spelling Lammermoor is an Anglicisation of the Scots Lammermuir. The Lammermuir Hills are a range of moors which divide East Lothian to the north from Berwickshire in the Scottish Borders to the south. The fictional castle Wolf's Crag has been identified with Fast Castle on the Berwickshire coast. Scott stated that he was not competent to judge of the resemblance... having never seen Fast Castle except from the sea. He did approve of the comparison, writing that the situation of Fast Castle seems certainly to resemble that of Wolf's Crag as much as any other.
