Adelaide is known as "the city of churches", for the high number of them there.

so is Brooklyn NY- when real estate developers were 'building communities' in brooklyn, they would often set aside some land for a church. then they would go to an over crowded church or synagoge in lower manhattan, and promise the land to the congregation if X number of members bought houses. so whole congregations moved from manhattan to the relative country of brooklyn, and build a new church on 'free land'. the churches are characterized by total lack of interesting architecture, the builder would often 'build the church/temple' as part of the deal.
