When we speak of monuments in America, we’re often talking about structures such as statues, obelisks, and memorials that celebrate a relatively narrow band of our history: the Civil War, the First and Second World Wars, the civil-rights era. Our monumental landscape preserves a sense that we are an exceptional, upstart nation. (American civilization may not boast standing stones that date back to the prehistoric era, but we do have Carhenge.) – The New Yorker
