History grade
What drives Palm Harbor’s History grade
On its age, its old homes and the National Register, Palm Harbor is more historic than 5% of U.S. towns, #558 of 638 in Florida. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
D
HistoryA character grade: shown, never part of Palm Harbor’s overall grade.
Few Florida towns list much on the Register (a typical Florida town has 0.0 per 10,000 residents, the U.S. 2.4), so Palm Harbor’s 0.0 sits below most of its state (33% of Florida towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D− to D. The pre-1940 share (±0.3 points) is firm at this size. The founding year is the first post office, not a stated founding date.

What stands out about Palm Harbor’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The area that is now Palm Harbor was largely uninhabited until settlers began arriving in the 1860s. The area became known as "Curlew", with the Curlew Pioneer Cemetery, established in 1869, and the Curlew Methodist Church. A post office named "Bay St. Joseph" opened in 1878. In 1881, Henry B. Plant, with the help of his 2nd cousin, Reino Milvid, opened the San Marino Hotel in what later became Palm Harbor in 1885. The Gulf View Hotel also opened around that time. The Sutherland Improvement Company acquired land in the Curlew/Bay St. Joseph area and developed it into the settlement of Sutherland. In 1888 the Sutherland Post Office opened. The Orange Belt Railway reached Sutherland in 1890.
The Palm Harbor post office opened in 1925, the earliest record of the town by name (U.S. post office records).
