Few Florida towns list much on the Register (a typical Florida town has 0.0 per 10,000 residents, the U.S. 2.4), so Lake Park’s 1.1 sits above most of its state (73% of Florida towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.

In 1923, it was officially incorporated as The Town of Kelsey City. It was originally named after Boston entrepreneur Harry Seymour Kelsey, after he purchased 30,000 acres (120 km2) north of West Palm Beach. The town was renamed The Town of Lake Park in 1939, and it was the first zoned municipality in the State of Florida. It was designed and planned by Dr. John Nolan of Boston, Massachusetts, and the Olmsted Brothers, the landscaping firm of Frederick Law Olmsted's sons, Frederick Jr. and John Charles.
