Tags: Prison.
The Black Dog was a prison in Newhall Market now Cornmarket in Dublin. The Black Dog was located in Browne’s Castle which became a tavern from which the prison got its name. From the early 18th century the Black Dog functioned as the main debtors’ prison in Dublin. The length of a prisoner’s stay was determined largely by the whim of his creditors. It was run privately for profit; beds could be rented from the head warder for one shilling a night.
