Boston's Cyclorama (now part of the Boston Center for the Arts) was built to house one of those massive static paintings, no scrolling. According to the BCA website:
" Cycloramas were a popular form of entertainment during the later nineteenth century. Most major cities in both Europe and North America had at least one. Built to house enormous, life size, panoramic murals, they frequently depicted battle scenes, evoking a sense of national pride while presenting graphic depictions of many historical events. The original painting for this Cyclorama depicted “The Battle of Gettysburg,” . . . Parisian artist Paul Dominique Philippoteaux, the leading panoramic muralist of the time, painted “The Battle of Gettysburg” in 1884. This massive canvas measured 50’ x 400’ and weighed 2.9 tons."
