A gibbet /ˈdʒɪbɪt/ is any instrument of public execution (including guillotine, executioner's block, impalement stake, hanging gallows, or related scaffold). 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 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".
