Marco Island is the largest and northernmost of Florida's Ten Thousand Islands. It is 28 miles south of Naples and its population in 2023 was nearly 16,000. Until the 1960s, the island was largely uninhabited.
The quiet isolation of Marco Island ended in 1964 when the Deltona Corporation bought the island and began to develop it as a resort and residential community laced with a network of dredged canals.
