Where was Spandau Prison located?

Spandau Prison was located in the borough of Spandau in western Berlin. It was constructed in 1876 and demolished in August 1987 after the death of its last prisoner, Rudolf Hess, who had died from a suspected suicide aged 93, to prevent it from becoming a neo-Nazi shrine. The site was later rebuilt as a shopping centre for the British forces stationed in Germany.

The prison, initially designed for a population in the hundreds, was an old brick building enclosed by one wall 4.5 m (15 ft) high, another of 9 m (30 ft), a 3 m (10 ft) high wall topped with electrified wire, followed by a wall of barbed wire. In addition, some of the sixty soldiers on guard duty manned 6 machine-gun armed guard towers 24 hours a day. Due to the number of cells available, an empty cell was left between the prisoners' cells, to avoid the possibility of prisoners' communicating in Morse code. Other remaining cells in the wing were designated for other purposes, with one being used for the prison library and another for a chapel. The cells were approximately 3 m (9.8 ft) long by 2.7 m (8.9 ft) wide and 4 m (13 ft) high.
