Most expensive prison - Spandau Prison, Berlin was originally built in 1887 for 600 prisoners, but for the 20 years preceding his death, the Nazi war criminal Rudolf Hess (b. 26 Apr 1894, d. 17 Aug 1987) was the sole inmate. In 1976 the cost of maintenance of the staff of 105 was estimated at $415,000 per annum. The prison was demolished in October 1987.
