Early in the 20th century, a unique retirement community was developed in North Florida. Lynn Haven, named for its founder, New Yorker William H. Lynn, was a haven for veterans of the Union Army and was promoted by the Grand Army of the Republic publication The National Tribune. In less than three years, its population grew to 2,500. Known as the only city south of the Mason-Dixon line boasting a monument dedicated to Union soldiers, the community has survived for almost a century. Featured here are scenes from the pioneer days to 21st-century development. These pictures record the progression of time and Lynn Haven's evolution into a traditional hometown amidst massive tourist development within Bay County.
