Richmond loves the sweet smell of history's roses, but it's the thorns that are on display at the Valentine Richmond History Center. "Battle for the City: The Politics of Race 1950s-1970s" examines the conflicts, protests and violence in the city during the civil rights era. The images on display include Ku Klux Klan meetings, riots after the assassination of Martin Luther King Jr. and the swearing in of Oliver Hill. The exhibit opens Friday, April 4, with a reception at 5:30 p.m. and continues through January 2009. 1015 E. Clay St. 649-0711.
