May's Island (or Mays Island) is a small island on the Cedar River, in Cedar Rapids, Iowa. Functioning as a civic center much like the Île de la Cité, it is the site of the Memorial Building (the city hall), the Linn County Courthouse, and the county jail. The island plus an adjacent block was listed as a historic district on the National Register of Historic Places in 1978. Read more on Wikipedia
