An article storage facility is disclosed that is capable of performing an appropriate transport operation on a container group even when a container group that includes a plurality of containers in a stacked state is placed on a placement surface in an inclined state. The control device performs inclination computation processing to obtain a placement inclination θ that is an inclination of a container group Cg placed on a placement surface F relative to a Z direction, based on coordinate information, bottom surface dimension information, and container group position information that are stored in a storage unit, and individual position computation processing to obtain individual position information that indicates a position, in X and Y directions, of each of the containers C in the tiers included in the container group Cg, based on the container group position information, the placement inclination θ, and the height dimension information, and controls a movement mechanism based on the individual position information.
