Concrete has the "advantage" of being un-recyclable. If you build your temple from stone blocks then it can be dismantled and re-used to build homes or heathen temples. Trying to disassemble a concrete structure will only yield either a crumbling mess, or a fireworks show in the case of implosion.

Ghost towns built from wood disappear after a couple generations. Youtube has some wonderful videos of people exploring abandoned soviet era concrete structures that I can stronlgy recommend.

I have considered advocating for the placement of concrete tubes as an alternative for tent cities, but concluded that it would backfire poltically.
