Pentonville prison

Today I helped a friend move house from north London to south of the river (I can confirm they have roads).
Dropping the van back at the rental place I realised it was near Pentonville Prison and went to have a look. Not sure of the era this frontage is from but it's an impressive structure - not easy to escape from i imagine. And a sign on the door says you get 10 years in prison for helping an inmate escape. I hope taking photos doesn't break the law.
I chuckled to see the cafe across the road is called Break Out!
