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 record the site of such places of execution.

Gibbeting is the use of a gallows-type structure from which the dead or dying bodies of criminals were hanged on public display to deter other existing or potential criminals. Occasionally, the gibbet was also used as a method of public execution, with the criminal being left to die of exposure, thirst and/or starvation. The practice of placing a criminal on display within a gibbet is also called "hanging in chains".
