The Grand Army of the Republic Memorial Hall, located in Nebraska City, Nebraska, was built in the Romanesque style in 1895 by Harry Lawrie and George Lee Fisher to serve as the gathering space for the William Baumer Post No. 24. The building, added into the U.S. National Register of Historic Places in 1985, is currently functioning as the Civil War Veterans Museum. The Grand Army of the Republic, known as G.A.R., was a fraternal organization to provide fellowship for the veterans of the Union Army after the American Civil War. The William Baumer Post No. 24 is one of the 354 G.A.R. posts in the state of Nebraska.
