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.

A jail tree is any tree used to incarcerate a person, usually by chaining the prisoner up to the tree. Jail trees were used on the American frontier in the Territory of Arizona, in the late 19th and early 20th centuries; jail trees were also used in Australia. A few jail trees survive to this day.
