The Old City Hall building, located in downtown Lincoln, was constructed as Lincoln’s first U.S. Post Office and Courthouse from 1874 to 1879 with Alfred Mullet and William Appleton Potter, Mulett’s successor, serving as project’s supervising architects from the U.S. Treasury. It functioned as Lincoln’s City Hall from 1906 to 1969, housing city agencies such as LAC Lincoln Arts Council afterward. The Old City Hall was the first building in Lincoln to be listed in the National Register of Historic Places in 1969.
