In ecclesiastical architecture, a ciborium ("ciborion": κιβώριον in Greek) is a canopy or covering supported by columns, freestanding in the sanctuary, that stands over and covers the altar in a basilica or other church. It may also be known by the more general term of baldachin, though ciborium is often considered more correct for examples in churches.
