Historians hope significance comes to light as Obama takes office
While the Lincoln Memorial on the far end of the Mall draws attention to the fight to end slavery, there is no memorial at the spot near the Capitol where slaves were once kept and sold in a three-story building called the Yellow House.
"Many people come down to the National Mall and never realize that they are walking on the site of the slave markets," said Jesse J. Holland, author of the recent book, "Black Men Built the Capitol." Now, with Obama's inauguration, historians are hoping that the role of slaves in the history of building Washington will become more widely recognized.
