When Barack Obama was announced victorious in the 2008 presidential election—the first African American to hold the nation’s highest office—he told the crowd of tens of thousands gathered in Chicago’s Grant Park, “This is your victory.”

Today was meant to mark another victory for Chicago—more specifically, for the city’s South Side. As Obama’s presidency comes to a close, his Foundation announced that Tod Williams Billie Tsien Architects (TWBTA), joined by Chicago firm Interactive Design Architects (IDEA), will design the Obama Presidential Center and Library.
