One aspect of the present subject matter relates to a concrete wall panel including a mounting system that includes a decorative panel with a flange embedded within the panel, the flange having mounting features providing for a number of ways to mount a plurality of such panels to a wall or other planar surface. The mounting system allows for fasteners to be used to connect the wall panel to a wall and provides a mount that has an air gap to allow for air to flow and for any moisture to pass between the wall inner surface and behind the wall panels.
