Re: I may be missing something
Churches do tend to be co-located with churchgoers, i.e. population spots. There are often telecommunications run out to churches, not least as a result of their role in WW2. There is also the possibility of line-of-sight microwave relay between the spires, should cabling not be available. There's also power run out to a church which isn't necessarily the case to these long abandoned rural outposts.
