Visited here twice for two of the tours (They have about 5 different ones). The place is truly amazing and the guides are full of interersting stories and facts.
The conditions for prisoners must have been truly horrid especially when you consider it was still a working prison up till 1991 - No sinks or toilets in the cells just a tin bucket.
Mind you serves them right I suppose - if modern prisons were like this there might be less crime.
Well wortha visit.
