Underground church, well, semi-underground. The religion has not been driven into secrecy - not yet - it has been built underground, as in a mine, in this hot dusty stark town of opal mining fame.
It is cool inside. Next door has underground rooms to stay in. The edge of town is a luna landscape of little mines with low piles of dirt - all to a certain height.
