The invention relates to a slaughtering and/or stunning apparatus as well as a method for slaughtering and/or stunning a slaughter animal. The inventive apparatus (1) comprises a rotatably mounted receptacle (18) with a drive-in side that extends within a first end wall (20), a holding mechanism (54) which is movable or pivotable in an opposite second end wall (22), and first and second sidewalls (32). In order to be able to slaughter animals in both a traditional and a ritual fashion, the receptacle (18) can be rotated by at least 180° while an opening (40) for ejecting the slaughter animal can be closed by the first sidewall (34) or a section thereof, said first sidewall (32) or the section thereof being pivotable or rotatable about a first shaft (36) that extends along the longitudinal axis of the receptacle.
