The old South Hall High School building erected in the late 1950s has entered into the 21st century with a new face: A digital face and two-tiered sanctuary for students. The old outdoor courtyard at the building — now called the Academies of Discovery, housing the DaVinci Academy of Choice and World Language Academy charter school — evolved into an arena full of modern architecture, comfortable lounge chairs and high technology. At the Monday meeting of the Hall County Board of Education, the new Learning Commons of the Discovery Academies was dedicated while students presented tours and baked goods.
