Era 1 · 1567–1881
Calusa capital at Mound Key
When the Spanish reached Mound Key near the mouth of the Estero River in 1567 they found the thriving capital of the Calusa. By the 1700s the Calusa had gone, leaving the area to Cuban fishermen, outlaws and pirates; around 1850 much of the coastal mainland was still under water.
