Although small, Bay City is one of the largest port cities on Lake Huron, one of the North American Great Lakes. It is part of a triangle of small cities in Central Michigan. The other two cities are Saginaw, Michigan, and Midland, Michigan.
Bay City was the birthplace in 1958 of Madonna Ciccone, a well-known American singer. The Scottish Pop group Bay City Rollers are said to have gotten their name from the city as well.
