The Lesesne House, Fernandina Beach Florida

Another double  shot for this location-  Historical Marker plus being on the National Register of Historical Places.  There were lots of Lesene's in Charleston SC as well.  

Inscription. This Classical Revival style residence, built by Dr. John F. Lesesne circa 1860, is one of the oldest homes in Fernandina Beach. Lesesene left Fernandina during the Civil War and did not return. In 1868 the house became the property of the family of Judge John Friend, who had been appointed district tax commissioner after the war by President Andrew Johnson. Friend was a lawyer and served as a county commissioner and judge. At the time of his death in 1878 he was state senator-elect from Nassau County. The descendants of the Friend family still occupy the home. This double galleried home, constructed of hand-hewn lumber fastened with wooden pegs, is one of the major points of interest in the Fernandina Beach Historic District which was listed in the National Register of Historic Places in 1973.

December 17, 2014 The Nassau County Courthouse (1891) Fernandina Beach, Florida

This courthouse was a triple-bagger as well, had a historical marker, is a courthouse, and is on the National Register of Historic places.  

It's just up the street a bit from the Post Office-  

The 1891 Nassau County Courthouse is one of only a few remaining courthouses in Florida built in the late 19th century. An excellent example of the Italianate style, it features a square domed tower with cupola, brick corbelling, bracketed cornice, brick pilasters, arched windows, granite sills, and arcaded entrances with cast iron columns. Its architect, A.E. McClure, was from Jacksonville, but designed notable buildings throughout Florida, including the Lake City Agricultural College, forerunner of the University of Florida. The building's cornerstone was inscribed with the date 1891 and was scheduled to be laid on December 16 of that year, but the ceremony was delayed until April 12, 1892. Renovations to the courthouse include the 1926 addition of a vault for the recording office and a bell that was cast by Meneely & Co. of West Troy, New York. The bell served as part of the city's fire alarm until the mid-1930s. The clock was added to the bell tower in 1977. The courthouse is the tallest building in the Fernandina Beach Historic District and has served the county's judicial and governmental needs since its construction.

December 17, 2014 The United States Post Office, (1912) Fernandina Beach Florida

This post office, which is listed on the National Register, is actually scheduled to be closed.  
When I visited, there was only one clerk on duty, and a long line.  I did get a cancellation.  
Originally built in 1912.  

As it looked in 1912

Today 

The United States Post Office, Custom House, and Courthouse is an historic building of the United States government in Fernandina Beach, Florida. It was constructed in the locally popular Renaissance Revival architecture style, and was completed in 1912 under the supervision of James Knox Taylor, Supervising Architect of the United States Treasury Department. The building sits at the intersection of 4th and Centre Streets, across from another historic Court House (c. 1898), and adjacent to the pre-Civil War Victorian Lesesne House (c. 1859). It is three stories, comprising 18,800 square feet (1,750 m²), including a basement and a partial attic. The United States District Court for the Southern District of Florida met here until the creation of the Middle District in 1962, at which time the building entered use by the Middle District of Florida beginning in 1962. The facility was also in use as a post office during that entire period. Other federal offices vacated the building in the 1930s-1940s, with the post office remaining only on the first floor. Some second and third floor space was used commercially into the 1990s, but the condition of the structure and lack of elevators ultimately led to the end those uses.

In 1989, the building was listed in A Guide to Florida's Historic Architecture, published by the University of Florida Press.

December 16, 2014 Martha's Hideaway or Hippard House, Atlantic Beach, Florida

Atlantic Beach was established in 1935- as the Negro Beach for the metro Jacksonville area.  It was started by a Mr Ervin, who was a wealthy life insurance executive.  Martha's Hideaway, also known as the Hippard House, was built as a getaway by one of Mr Ervin's family members, and it was reputed that lots of gambling and perhaps other activities took place here.  
It went on the National register in 2001. 

American Beach, founded in 1935, was a renowned beach for Blacks during the segregation era when African Americans could not go to public beaches. In the early development of American Beach, a few private homes were built, including one hidden deep in the woods at the end of Ervin Street. The Colonial Revival house, built for local African-American business owner and community activist Martha Hippard, is an unusual example of high style architecture in the beach resort community. Detached from the main house is a separate party house that some say was a gambling house. Others say it was used to host dances, club parties, and other civic and social activities. Both houses are constructed of hand-made concrete blocks from truckloads of crushed coquina shells hauled from American Beach and hand-molded bricks manufactured on the premises. The 1938 structures were built on nearly an acre of land, larger than any other parcel in the area. In January 1961, Elmo and Annette Myers of Fernandina purchased the house from its second owner, educator Lottie O. Harris of St. Mary's, Georgia. Martha's Hideaway, also called Hippard's Hideaway, was listed on the National Register of Historic Places on October 12, 2001.
