Brothers Jules & Jack Freeman established San Carlos Park in 1953 in hopes of providing low cost homes for the middle class. The Freeman group purchased their land from the Koreshan Unity who gave them almost 250 acres for just under $3,000. When they acquired the land in Estero, Florida, they found that it was in the middle of nowhere, with the county seat, Fort Myers, Florida, being over 20 miles away. In the 1970s, the Freeman's drilled down into the ground and hit a spring, this spring would become a local attraction located at the San Carlos Park arches Later on in the mid-1970s the Freeman group would go on to begin construction of their next community Three Oaks, Florida.
