The Big Bay Point Light is a lighthouse which stands on a tall bluff over a rocky point near Big Bay, Michigan, approximately 24 miles (39 km) miles northwest of Marquette on the Upper Peninsula of Michigan. Today it is the only operational lighthouse with a bed and breakfast. It is reputed to be haunted, and the novel and movie Anatomy of a Murder were inspired by a murder rooted at the lighthouse.
