cathedrals (and many churches) and busy community centres with far reaching benefits to the whole society, as well as hubs for religion, music and history.
I said this upthread, but I'll say it again here.
Most winter shelters for rough sleepers in London are in churches, around 19/20. Most refugee centres and food banks are run out of churches, ( and most refugees sleeping rough in London are Muslim, not Christian)
Most toddler groups and brownies/cubs etc are run in churches, many music schools and choirs, etc.
There are three churches in our high street, two will be open for tea and coffee right now. One is open every single day to serve tea and coffee, and runs a youth club several evenings a week.
One has three separate churches running from the same building, one English speaking, one Polish speaking and one African. Each congregation has a Sunday service, a couple of weekday services, a womans service, a worship practice, planning and admin meetings, bible study, etc, as well as the toddler groups and holiday clubs etc they run together.
The idea that churches are only used a couple of hours a week is quite weird.
