Ancient ruins theme

A stage that has an ancient ruins theme features a setting or significant sections with ruins of buildings in the background or on the course. In many instances, Sonic must run on or among the ruins; in other instances, the ruins are only seen in the background of the level.

Common elements include structures that are or have fallen apart, or ancient structures that have fallen apart but are nevertheless dilapidated or simply abandoned. Unlike several other themes, this theme does not feature special enemies.
