Corbels, used as supports(brackets)
Those in the photograph look as if they have had beams or joists resting on them to support a floor/ceiling. Probably sandstone, not overly decorative but decorative enough to remain on show. Likely to be twice as much again of what's showing inserted into the wall/ pillar.

God help us,
Don't send Jesus,
This is no place for children.
