content: D.C. has been designed that way deliberately. It's not just the Lincoln Memorial, the Jefferson Memorial, the White House, Capital Hill, the IRS building, the National Gallery, the Academy of Sciences, and some 50+ other buildings in the D.C. area are designed in a neoclassical style to model Rome. Not only that, the United States has the highest concentration of neoclassical architecture in the world. Its also specifically roman as opposed to greek, because if there's an inscription that isn't in english-- it'll be in latin.
