Tampa Bay toponymy: The origin of Pinellas County place names

We looked at why the places in and around St. Pete are named what they’re named.

A pelican stands close to the camera on a wooden beam which appears to be part of a pier. There is blue water which is slightly rocky stretching into the distance behind the bird, and a distant landscape with trees + waterfront houses on the horizon. The sky is pale blue with a smattering of clouds.

What’s in a name? As it turns out, quite a lot.

We’re indulging in some linguistics today, specifically with a look at local toponymy, the study of place names. For the first installment in the series, let’s dive into the name origins of some notable Pinellas County locations.

Pinellas County

The county itself gets its name from the combination of the Spanish punta pinal, which translates to “point of pines.” This was an accurate description of the area’s natural beauty when its first European inhabitants landed in the 16th century.

St. Petersburg

Pinellas’ largest city has fascinating toponymic roots. Legend says St. Petersburg was named by Peter Demens, an exiled Russian aristocrat, thanks to the flip of a coin. However, this myth has been debunked, and history suggests Demens named the city after where he was born. The coin story is more fun.

Safety Harbor

The quaint city’s name has roots in the early 18th century, at which point pirates roamed the seas around the Tampa Bay area. Once boaters traveled up Old Tampa Bay to Safety Harbor, they were no longer in danger.

The pier in Safety Harbor juts out from the left of the screen. A long boater rides along calm dark blue waters as pale sunlight graces the scene. It appears to be sunrise, and there are a few clouds in a mostly blue sky.

A welcome sight for those evading pirates.

Treasure Island

Speaking of pirates, property owners in Treasure Island engaged in an element of skulduggery themselves. During Florida’s land boom of the early 1900s, owners boosted home sales by “burying and then ‘discovering’ wooden chests on the beach” claimed to be full of treasure, enticing folks to the area.

Pass-a-Grille Beach

There are several theories for this one. A popular explanation is that fishermen camped at a stretch of the island called “Passage of the Grillers,” where they grilled up their fresh catches. We took a deep dive into Pass-a-Grille’s history.
