execution chamber at the
Red Hat Cell Block in the
Louisiana State Penitentiary in
West Feliciana Parish. The
electric chair is a replica of
the original. In the United States, an execution chamber will usually contain a
lethal injection table. In most cases, a
witness room is located adjacent to an execution chamber, where witnesses may watch the execution through glass windows. All except for two of the states which allow
capital punishment are equipped with a death chamber, but many states rarely put them to use. The exceptions are
New Hampshire, which has no execution chamber (although one inmate remains on death row since the abolition of capital punishment in that state is not retroactive) and
California, which has no execution chambers after the
lethal injection room and
gas chamber were removed in 2019.
Kansas,
Nevada, and
Wyoming are the only states to have an execution chamber, which is equipped to execute an inmate by lethal injection, which has never been used, while the states of
New Jersey and
New York formerly had lethal injection chambers which were never used while the death penalty remained legal. The National Ethics Council of the
American Institute of Architects ruled in 2019 that its members may continue to design execution chambers in jurisdictions where they are legal. (however "Rule 1.402 would preclude a member from designing a facility intended for torture ...").
