After years of litigation, preservationists have lost the battle to save Richard Neutra’s Gettysburg cyclorama building, an iconic example of modern architecture from the 1960s. The bulldozers could raze this circular visitor center as early as February, the Philadelphia Inquirer reported. The National Park Service commissioned the glass and concrete building as part of its Mission 66 initiative—a billion-dollar program to update park services across the country—at the Gettysburg Battlefield site.  The rotunda was designed specifically to house the 1883 panoramic painting of the Battle of Gettysburg by Paul Philippoteaux.

Modern architecture preservationists and Civil War buffs clashed over the future of the building, which resulted in legal action that required the National Park Service to conduct a review of the demolition and explore alternative solutions. But when Paul Philippoteaux’s painting was relocated to a new visitor center, the fate of Neutra’s building seemed sealed. The National Park Services released its report this past September and determined that there was no other alternative but to tear the building down. The Gettysburg Foundation will pay for the $3.8 million demolition.
