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.
