Built in 1796, Kilmainham Gaol was the official County of Dublin Gaol.
Hanging was a common punishment for all sorts of crimes.
Public hangings took place at the front of the gaol where people gathered to watch the death throes of the condemned person.
Prisoners were not segregated.
Men, women and children were incarcerated up to five in each cell, with only a single candle (replaced once a fortnight) for light and heat.
Many children arrested for petty theft were lodged in Kilmainham with adults until they were dispersed to various reformatories situated around the country.
Many adult prisoners who were not hanged were transported to Australia.
