In the United Kingdom, the execution chamber was part of a larger complex, often referred to as the "Execution Suite". The room, usually formed from two single prison cells, contained the large trapdoor, usually double-leaved, but in some older chambers such as at Oxford, single-leaved, and operating lever. The wooden beam from which the rope was suspended was usually set into the walls of the chamber above, with the floor removed. At Wandsworth Prison the floor was retained and holes allowed the rope and chains through. Oxford's chamber was of an old 19th-century type, and the beam was set into the walls of the chamber just above head height.
