Pennsylvania's state song mentions the state nickname in the second verse: "Birthplace of a mighty nation, Keystone of the land." A keystone is also featured on the U.S. Mint's commemorative Pennsylvania quarter. The word keystone is from architecture, it describes the central wedge-shaped stone in an arch which holds all the other stones in place.
