This collection of caches has nothing to do with the Church Micro series in the UK. Given that the Australian 2016 census indicates that No Religion and Jedi Knight are the fastest increasing classifications of the optional religion question "What is the person's religion?" it is not surprising that there is surfeit of empty churches that have been repurposed.
St Francis Xavier Seminary chapel, Rostrevor. Opened 1959. Closed 2001. The red brick building has been recently sold as a private residence with headlines including "Chapel conversion: Plans lodged to turn house of worship into grand home" and "Rostrevor church conversion in need of divine intervention."
The new residence has a street number. Use the street NUMBER that can be found at the reference waypoint and the listed coordinates to calculate the location of the nearby cache.
