What stands out about Port Salerno’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
In the 1920s, a small settlement was created in the southern shores of St. Lucie river inlet. It was named "Salerno" because of its visual resemblance to the Italian city of Salerno as observed by an early visitor. Early settlers were fisherman who lived along the banks of the Manatee Pocket, a small natural bay in the St. Lucie River. Some descendants of these original settlers remain in the area, with some families owning land for over 100 years.
The area increased in population and importance after World War II, with many people from the northeastern United States moving to Florida. In 1960, the name was changed to "Port Salerno", in order to differentiate it from that of the Italian city.
