Cathedral is a stage in Tekken 5. It is a cathedral with reddish-orange windows. Blue-flamed torches and a statue of a Devil-like creature with wings wielding a sword can also be seen in this place. The Devil-like creature appears to be standing over a Cerberus-like (three-headed dog) creature. Gates and walls surround the fighters. This is where a player fights Devil Jin, the sub-boss in Tekken 5 (with some exceptions in Tekken 5's story mode).

If fighters are launched into the walls of this arena, the glass shatters, causing fragments to fall to the floor. Bats can be seen when a player falls heavily on the ground.

This stage's Tekken 5: Dark Resurrection parallel is the Winter Palace.
