As membership declines, just wondering what happens to all the cash the Churches are sitting on, from property, to art, to chuch tax collections. Going to be interesting to see what the next (younger) gen of church leaders do with it...maybe they need an innovation center to modernize the useful aspects of religion.
In my Dutch town, there are churches that have been converted to hotels, a night club, several bicycle parkings, an award-winning bookshop that promptly went bankrupt, an indoor playground and a slew of restaurants. Others are just torn down. It seems the church has a preference for the last, but many of the expensive ones to maintain (i.e., the ones they want to get rid of first) are monuments and have to be preserved. There is one I can see from my window that has been under renovation for 20-something years; every couple of years there is a 'competition' to find someone with the best plan of what to do with it, and they never find anyone because a) it's a monument so you're very restricted in what modifications you can do with it; and b) it's very expensive to maintain (let alone renovate).
So yeah, whatever money they have remaining in art etc has been dumped into pretty much worthless property over the last decades. A few of the remaining nuns around my corner distribute a door to door church flyer once every few months (blissfully ignoring any 'no advertising' stickers on any mailbox, bless their hearts), and they report on the financial state of the parish in it every once in a while - judging from how excited they sound when they've collected a few 100 at a service that drew a large crowd, it's not all glitter and gold in the church (at the lower levels at least). Oh and another church around the corner (I have literally a dozen within a 1km radius from my house) sells christmas trees from their parking lot every year to keep the heating on - not exactly a sign of opulence either.
