The Mediterranean revival style building displays Italian renaissance influences and contains many intricate exterior details. The building's open style was extensively promoted in the 1920's as proof of St. Petersburg's balmy climate.
In 1969, portions of the building were enclosed to allow for indoor service counters, air conditioning and heating, and additional postal boxes. On April 4, 1975, it was added to the U.S. National Register of Historic Places.
Inside the Post Office is also a very tiny postal museum in the back that contains an old leather mail bag, typewriters, and old postcards showing the historic Post Office. The employee that I purchased postcard stamps from was very nice and told me that they used to have a special postmark, but sadly are no longer allowed use it.
If you are ever in St. Petersburg, FL, I suggest making a stop to see this historic Post Office. Be sure to drop a few postcards off in the letter drop while there too.
