A genuine steel beam from the ruins of the World Trade Center rests atop a brushed-steel replica of the Twin Towers. Soil from Pennsylvania and a Pentagon-shaped planter constructed of Indiana limestone, the same material used in the face of the Pentagon, accompany foliage common to the Shanksville area to represent new life. The beam journeyed from beneath the ruins of Ground Zero through the hands of armed services and firefighters before finally coming to rest atop the polished replica, a piece reunited with its whole. Severely damaged but not completely destroyed, this World Trade Center artifact serves here as a foundation for the beliefs that bind the nation: life, liberty, and the pursuit of happiness.
