Cave Walls are naturally-generating background walls found throughout caves in both the Underground and Cavern layers. These naturally occurring walls can be destroyed with a hammer, but will drop nothing. These walls also do not stop enemies from spawning and cannot be used for proper housing.
On the Old-gen console and versions, the Rocky Dirt, Old Stone, Cave Dirt, and Rough Dirt Walls are the only walls that will generate due to those being the only ones that exist in those versions.
On the Desktop version, these walls can be crafted with their respective materials where they can be used like other craftable walls.
