and Libby Building, which operated as Libby, McNeill and Libby's main Midwest processing plant from 1918 to 1968, is a prominent historic remnant of Blue Island's industrial heritage, located three blocks south of downtown Blue Island on Western Avenue. The American House One of the oldest buildings in Blue Island, the American House was built in 1839 as the courthouse for Lake County, Indiana—a function it never actually had the chance to serve, as the county seat was moved from Liverpool to Crown Point in 1840. In 1844, the building was disassembled, sent by raft up the Little Calumet River, and reassembled in Blue Island.
