Many many church goers flocked to this sacred site then later the numbers declined.  Mount St Alphonsus monastery became empty,  pervaded with solitude and changed to a non-denominational wedding venue (according to the signage).
The members of the well know international religious order who built the monastery, came to Singleton in the Hunter as their first port of call in the early days and have recently left the Hunter area possibly for ever.
The large size of the monastery of 1887 makes it unique in Newcastle.
New innovative uses for the building can be imagined if we happened to have a bigger population.
If in doubt, turn it into a wedding venue (or aged care)!  Secular society still likes to hark back to vestiges of a church wedding. Same with Christening - some people like the idea - that's it.  Baptism can become useful with spin offs to do with church schools and the like.
