The Cyclorama's final day open to the public was June 30, 2015, after which it closed in preparation for the move. The History Center began construction in fall 2015 on a new building to house the painting, the diorama and the "Texas" locomotive. During the construction, restoration work was done on the painting, including the addition of areas of the painting that were removed prior to its installation in the current Grant Park facility. After the History Center building was completed, the painting and diorama were to be moved to the new facility where restoration continued, at times in view of History Center visitors. The building in Grant Park will be given to Zoo Atlanta, which will use it as office and event space, including a new private viewing area for a proposed expansion of the zoo's African elephant habitat.
