Dule trees, or dool trees, in Britain were used as gallows for public hangings. They were also used as gibbets for the display of the corpse for a considerable period after such hangings. These "trees of lamentation or grief" were usually growing in prominent positions or at busy thoroughfares, particularly at crossroads, so that justice could be seen to have been done and as a salutary warning to others. Place names such as Gallows-Hill, Gallows-See, Gallows-Fey and Hill of the Gallows (Tom Nan Croiche) record the site of such places of execution.
