The National Historic Landmarks in Michigan represent Michigan's history from pre-colonial days through World War II, and encompasses several landmarks detailing the state's automotive, maritime and mining industries. There are 42 National Historic Landmarks (NHL) in the state, located in 18 of its 83 counties. The landmarks also cover sites of military significance, such as Fort Michilimackinac, religious significance, such as the St. Ignace Mission, and cultural significance, such as the Fox Theater and Ernest Hemingway's boyhood summer cottage. In addition, two previously designated landmarks have lost that status due to the demolition of the sites.
