Remember Garrow's Law on TV

This was part of the set, the road leading to the Gaol.
This was seen many times as the illustrious William Garrow went to meet his unfortunate clients who had very little chance of a fair trial.
I read a bit about Garrow and we would not have the justice system we have now were it not for men like him.
Cyber pint for anyone who can tell me where it is !!!
