Why did the stones used on the Lincoln memorial come from different states?

From the chamber of the memorial, one can appreciate the different stones used in its construction. The terrace walls and lower steps comprise granite blocks from Massachusetts - the upper steps, outside façade, and columns contain marble blocks from Colorado - the interior walls and columns are Indiana limestone - the floor is pink Tennessee marble - the ceiling tiles are Alabama marble - and the Lincoln statue comprises 28 pieces of Georgia marble. These building materials may seem random, but Henry Bacon specifically chose each one to tell a very specific story. A country torn apart by war can come together, not only to build something beautiful, but also explain the reunification of the states.
