Shell works are amazing structures built by ancient people in southwest Florida. They are made mostly from huge amounts of shells. Imagine giant piles and shapes created using shells! These shell works include mounds, canals, walls, and even special "water courts."

The biggest shell works were built a long time ago, during the Woodland period. This was in southwest Florida, stretching from Charlotte Harbor all the way to the Ten Thousand Islands. This area also includes places like Estero Bay.

What Are Shell Works?

Shell works are like ancient towns or villages built from shells. They are not just random piles. They are carefully planned and shaped. Some shell works cover a huge area, from about 20 to 125 acres (8 to 50 hectares). The mounds within them can be really tall, sometimes 5 to 10 meters (16 to 33 feet) high!

Famous Shell Work Sites

A long time ago, an explorer named Frank Hamilton Cushing studied the Charlotte Harbor area. He found over 75 artificial islands made of shells! These islands varied in size.

Some of the most famous and largest shell works include:

  • Mound Key: This site is huge, covering about 128 acres (52 hectares).
  • Chokoloskee Island: This island is over 0.5 miles (0.8 kilometers) wide and can be up to 27 feet (8 meters) high.
  • Pineland Archeological District
  • Dismal Key
  • Fakahatchee Key
  • Russell Key

Important Shell Work Sites

The Turner River Site is another important shell work. It's located near Chokoloskee Island. This site covers about 40 acres (16 hectares) and is 0.25 miles (0.4 kilometers) long. It was the first shell work in the Ten Thousand Islands to be studied by professional archaeologists. It was added to the National Register of Historic Places in 1978.

Another significant site is the Mark Pardo Shellworks Site. It's found in Cayo Costa State Park near Bokeelia. This site was added to the National Register of Historic Places in 1996.

Life on Shell Works

When Europeans first arrived in Florida in the 1500s and 1600s, they saw people living on some of these shell works. They wrote about houses built on top of the mounds. They also described how different parts of the shell works were used for special ceremonies. This shows that these shell structures were important centers for daily life and cultural activities.

Studying Shell Works

People started to study shell works in the late 1800s. At first, archaeologists had different ideas about what they were. Some thought they were just ancient trash piles, called middens. Others believed they were monuments, burial mounds, or platforms built to keep homes safe from floods.

Early archaeologists were amazed by how complex these sites were. They were much more complicated than simple mounds found in other parts of Florida. This showed that the people who built them had advanced skills and a clear plan.
