(Gettysburg) -- Demolition is under way at Gettysburg National Military Park on a building situated at the center of what were once the Union Army's lines.
Park spokeswoman Katie Lawhon says the work to tear down the Cyclorama Building began with asbestos removal a month ago and is expected to last until late April.
The removal is part of the park service's longstanding efforts to restore the park to conditions more closely mimicking 1863, when the property was the site of a pivotal battle in the Civil War.
The nearly $600,000 dollar cost is being paid by the Gettysburg Foundation.
The Cyclorama building was designed by famed architect Richard Neutra and once housed a 360-degree painting of Pickett's Charge.
The structure, which closed in 2005, has been the center of a struggle between the park service and modern architecture experts for more than a dozen years.
