BEARDSTOWN, Ill. (AP) — Efforts are underway to digitally preserve a central Illinois courthouse where President Abraham Lincoln defended a man against a murder charge. Special 3-D scans were done Wednesday at the courthouse in Beardstown where Lincoln defended William Armstrong in the so-called Almanac Trial of 1858. The building is now called the Old Lincoln Courtroom and Museum, and houses thousands of local artifacts. Global organization CyArk is working with U.S. Laser Scanning of Morton on the courthouse project. Bob Hohimer Jr. with U.S. Laser Scanning says the scans mean there will be exact measurements of the building in case it ever needs to be rebuilt. Paula Woods, chair of the Old Lincoln Courtroom and Museum, says the courthouse has seen flooding in the past.
