St Lucie County was given the name by the Spanish after they began construction of a fort on December 13, the feast day of the Roman Catholic St Lucia . The St Lucia colony was established in 1567 near Vero Beach and Stuart. In the 1900s the Anglo-Saxon version of St Lucie was identified.
During the 2nd Seminole, the US Army set up posts in the state and in 1837 Colonel Benjamin Pierce sailed Indian River from St Augustine southward and 1 year later he built a fort out of Palmetto trees near Ais Indian Mound known now as Old Fort park.
In 1894 the 1st steam locomotive on the Florida east coast rail way came to Ft Pierce. With rail expansion, it helped to create a population boom in the area and helped to transport pineapples from Cuba.
