Glen Parva Juvenile Prison, Feb 2018

[Yorrick]

It was the biggest young offenders unit in Europe. The tunnel/corridor is just under a mile long and the units run off each side of the corridor.

I think you may be thinking of somewhere else. The whole site at GP is under 500 metres long.

Hi,
No it was definitely Glen Parva. I've probably got my measurements a little wrong, it's been that long ago !
