I grew up in a small town of 4000 souls in New York State -- the other examples here are Bible Belt or Europe, I think, and NY is somewhere closer to the D&D norm. That is, it's not a state religion, one-church per town set up like most of Europe traditionally was, and it's not an American Bible Belt, no hierarchy, every-family-has-its-own-flavor of Protestantism situation.
So far as I can remember, we had four religious establishments in town:
- The Community Church. "Non-denominational" Protestant, which more or less meant Episcopal, I think, but was open to any Christian. Image a temple of Pelor that also welcomes worshippers of any good god in the same pantheon -- St. Cuthbertines replacing Lutherans, perhaps, and Heironeous replacing Presbyterians, etc. A modern building, in the center of town, next to the public elementary school, the only restaurant, the little grocery store, the library, Conant Hall, and the nursery -- our one export business.
- Conant Hall. A tiny little church in the heart of town. It was replaced by the bigger building of the Community Church, and bought by the town. It was used for meetings of the historical society (replace for D&D with the militia) and for elections (town hall meetings of the populace to deal with the goblin threat!).
- The old, old colonial era Congregational Church. This church was a little more hard corps Puritanical in its services, and had been there since before the Revolution. It was out in the middle of the woods. This is the parallel to ancient druidic center, perhaps a shrine to Obad-Hai ("The Old Faith").
- A tiny Buddhist temple started by a few converts in somebody's house out in the woods. These guys were a little infamous when I was in high school, among other things for banging gongs at dawn on Saturdays, which annoyed the neighbors. They got an injunction, but the Buddhists sued and won a lot of money -- which used to restore some of the historical buildings in town, including Conant Hall. Replace this misunderstood group with an evil cult in your village -- rumored about, out in the woods, annoying the neighbors, but the town is powerless to stop them, because of some higher authority or fear of them. And some folks think they are nice.
So my "typical village" might have:
- 1 mainline temple of a major good god
- 1 druidic/neutral shrine, or other minor good shrine
- possibly another historical or currently not used as a church building
- a secret cult in the woods, which most people know about and whisper about.
