The gaol's place of worship was a chapel located inside a round building in the centre of the radiating residential and service 'arms' of the prison.
Its centrepiece was three leadlight windows depicting the New Testament story of the prodigal son who after confessing his wrongdoings and repenting was forgiven by his loving father.
The words written on an open scroll at the top of each window are:
I say unto you that likewise joy shall be in Heaven over one sinner that repenteth more than over ninety and nine just persons which need no repentence.
Above the three windows is a painted white dove, the symbol of the Holy Spirit, and the words:
Glory to God in the highest.
Prisoners at the gaol attended church services in this circular building.
It originally had an extra floor which was used to segregate the prisoners on the basis of gender. The female prisoners were seated on one level and their male counterparts on the other.
