People have used this site for more than 700 years. George and Olivia Adderley lived here from 1903 to 1949, making charcoal and gathering sponges to sell. Francis and Mary Crane bought the property in 1949 and added a causeway to Big Rachel Key. The Adderley House is a highlight, but sources disagree on whether it was built in 1903 or 1904, so the exact year is best left open.
The Florida Keys Land Trust formed to protect the Keys’ hardwood hammocks and bought Crane Point in 1989, when homes and a shopping center were planned for the land. The organization later became the Florida Keys Land and Sea Trust; the preserved campus is a tangible reminder of what could have replaced this patch of habitat.
