A panel adapted for mounting on a building, the panel being formed from a plurality of thin panels of a selected stone facing material, such as granite or marble, backed and interconnected by fiberglass-strengthened concrete underlaying the plurality of thin panels and covering and engaging anchor means mounted in the backs of the stone panels. The method of forming the building panel involves placing the granite or marble panels face down in a form, mounting anchor means in the backs thereof, and overlaying both the plurality of thin panels and the anchor means with a fiberglass-strengthened concrete mixture, and curing the mixture both within and without a support form.
