A slice of Old Florida history and unparalleled privacy has hit the market. A secluded private island near Naples, complete with a meticulously preserved 1920s mansion, is now being offered for a staggering $89 million.

The crown jewel of the estate is the main residence, a circa-1928 house built by the renowned inventor and electrochemist Charles F. Burgess. The home stands as a testament to its era and its original owner's innovative spirit. Burgess, a figure deeply embedded in the scientific community of his time, famously hosted fellow luminaries like Thomas Edison within these walls, adding a layer of historical significance to the property's considerable allure.

The estate promises an exceptional level of seclusion, accessible only by boat or helicopter. Beyond the historic mansion, the island offers extensive grounds for potential development or preservation, presenting a rare opportunity to own a piece of Florida's gilded-age past with all the modern potential for luxury living. The listing captures a unique blend of architectural heritage, scientific history, and absolute privacy on the Gulf Coast.
