The Millenary Secret on the Sea of Canasvieiras
If you are planning a paddle to Frenchman's Island (Ilha do Francês), prepare for more than just crystal-clear waters. Beneath the island's rocky shores lies a historical treasure of 5,000 years: the Lithic Workshops.
Frenchman's Island is much more than natural beauty; it is an archaeological site. Among the granite rock formations on the island’s southwest side are the famous Lithic Workshops.
We, at Adventure in Floripa, invite you to paddle with us and uncover the mystery of these vestiges and why they are crucial to understanding the pre-history of Santa Catarina.

What Are Lithic Workshops? Where the Past Was Forged
The Lithic Workshops are living proof of the intelligence and adaptation of the ancient peoples who inhabited the coastline. They were not simple holes; they were fixed work sites used by pre-colonial populations, known as the Sambaqui People.
How to Identify and What Were They Used For?
Lithic Workshops are easily identified as depressions, grooves, and friezes carved into hard rocks like basalt or granite, such as those found on Frenchman's Island.
Production Benches: They served as natural "benches" for the crafting and polishing of stone tools.
Survival Tools: They were used to sharpen and shape essential artifacts like axes, spear tips, and grinding instruments.
The Process: Ancient peoples used sand and water for abrasion against the rock, leaving the distinct marks we see today.
The Historical Significance of Frenchman's Island
The presence of these vestiges on Frenchman's Island is not coincidental. It proves that the small island, close to Canasvieiras Beach, was a:
Strategic Production Point: A safe and isolated place for processing hunting and fishing materials, away from the main villages on the mainland.
Harmony with the Sea: It demonstrates how ancestral peoples lived in perfect synchronicity with the marine and terrestrial ecosystems of the region.
SC Heritage: Just like other important archaeological sites in Florianópolis, this location must be protected.
