The Pinnacle Chapel is a grassy area with a church found in Dragon Quest IV's secret dungeon in Chapter 6 after having beaten the game. It is of utmost importance since it is the only place the party can zoom to in the dungeon. This facilitates the progression of the dungeon as well as the level grinding since in the area next to it lies the area where the Platinum King Jewel lies. This area also allows the Wagon to be used and thus lets the player change any party members they want or cast spells that current party members don't have.
No monsters are found here even though it is inside a dungeon and only one NPC exists here which advises the party to go to the church before going further in. The area however still counts with dangers since it counts with several poison puddles; one of which protects a chest.
