Church

A Church, Clinic, Sanctuary, or Revive Pool was a means of reviving party members in the first three Final Fantasy games. Reviving characters in a Church usually costs a small fee. It was later on that Phoenix Downs and Raise became the main source of revival and so the concept of Churches or Revive Pools were scrapped altogether, except as plot devices.

Final Fantasy
Churches, originally known as Clinics in the North American Nintendo Entertainment System release due to Nintendo of America's at the time policy of removing religious elements from American ports, are found in all towns and villages in the World Map except Melmond. As the player goes on to towns farther than Cornelia, the cost of reviving a party member increases.

Final Fantasy II
Sanctuaries appear in most towns and villages in the World Map. They appear as unmarked buildings with statues of a goddess inside. Examining the statue will revive all KOed party members in the party with a meager amount of HP at no cost.

Final Fantasy III
Revive Pools are found in many towns, areas, and castles in the World Map. They usually appear along with Healing Springs and have the effect of reviving party members without any cost.

Compilation of Final Fantasy VII
A church makes an appearance in the Compilation of Final Fantasy VII as Sector 5 Church. It is an important place within the story and is usually associated with Aerith Gainsborough as she tends flowers here.

Final Fantasy IX
As a likely allusion to the NES generation of games, several of the major cities include chapels. Alexandria's chapel is near the western dock, where Moogles Kupo, Stiltzkin, and Artemicion make appearances throughout the course of the game. The chapel in Lindblum is located in the Business District and is currently undergoing maintenance.

Additionally, other locations such as Gizamaluke's Grotto, Esto Gaza, Conde Petie, and the Cleyra Settlement seem to be religious centers. There are no house chaplains offering services of game-saving or character revival, but the empty chapel in Alexandria holds the first location in the game where one can use a moogle to save one's game, use a Tent, or begin the Mognet sidequest.
