Alpena Light

The Alpena Light, also known as the Thunder Bay River Lighthouse or Alpena Breakwater Light,^[5] is a lighthouse on Lake Huron near Alpena, Michigan. Standing on the north breakwater of Alpena Harbor, the light marks the entrance to the Thunder Bay River from Thunder Bay.^[5] The current lighthouse, built in 1914, replaced earlier wooden structures which had been in use since 1877 and 1888.^[12] The current light is a weather-protected structure on a steel frame. It was added to the National Register of Historic Places in 2006, and the state inventory list the same year.^[13]
