Correctional facility in the context of "Imprisonment"

A penal colony or exile colony is a settlement used to exile prisoners and separate them from the general population by placing them in a remote location, often an island or distant colonial territory. Although the term can be used to refer to a correctional facility located in a remote location, it is more commonly used to refer to communities of prisoners overseen by wardens or governors having absolute authority.

Historically, penal colonies have often been used for penal labour in an economically underdeveloped part of a state's (usually colonial) territories, and on a far larger scale than a prison farm.

A prison farm (also known as a penal farm) is a large correctional facility where penal labor convicts work — legally or illegally — on a farm (in the wide sense of a productive unit), usually for manual labor, largely in the open air, such as in agriculture, logging, quarrying, and mining. In the United States, such forced labor is made legal by the thirteenth amendment to the Constitution; however, some other parts of the world have made penal labor illegal. The concepts of prison farm and labor camp overlap, with the idea that the prisoners are forced to work. The historical equivalent on a very large scale was called a penal colony.

The agricultural goods produced by prison farms are generally used primarily to feed the prisoners themselves and other wards of the state (residents of orphanages, asylums, etc.), and secondarily, to be sold for whatever profit the state may be able to obtain.
