The Fountain of Youth Archaeological Park is a privately owned 15-acre (61,000 m2) park in St. Augustine, Florida, located along Hospital Creek, part of the Intracoastal Waterway. It has been touted as the likely 1513 Florida landing site of Spanish explorer Ponce de Leon, although no evidence has been found to substantiate this claim. Recent research by amateur historian Douglas Peck has placed another possible landing site in the vicinity of Melbourne Beach in Brevard County.The park contains a well claimed to be the freshwater source referred to by Antonio de Herrera y Tordesillas in his Historia general de los hechos de los castellanos en las Islas y Tierra Firme del mar Océano and supposedly sought by Ponce de Leon, but there is no supporting evidence. Archaeological excavations made by Dr. Kathleen Deagan on the park's grounds in the 1990s uncovered remains of the first Spanish settlement and its fortifications in St. Augustine.

The Horace Walker House, also known as Castillo Sebastian is a historic home in St. Augustine, Florida built around 1888. It is located at 33 Old Mission Avenue, near the north city gate. On January 30, 1998, it was added to the U.S. National Register of Historic Places. The house was erected using mold-formed concrete blocks, commonly called "artificial stone". Smith was the first to make concrete blocks that used crushed coquina instead of sand, along with Portland cement. In the late 19th century, this type of construction was new but the blocks used display the same characteristics: smooth/rough opposite surfaces, plus iron rods used for structural reinforcement. The two-story, two bedroom, two bath house is one of St. Augustine's smallest examples of Moorish Revival architecture. The flat roof with decorative parapets are typical for the style; as is the front porch with five Tuscan arches—three facing the street. The interior is ornate, with heart of pine floors; the doors and ceilings feature carved wood. The central element is a double staircase with a landing between.The structure was designed by Franklin W. Smith, who also constructed Villa Zorayda, his personal residence in St. Augustine, and the Casa Monica Hotel, which was sold to Henry Flagler.

The Huguenot Cemetery (also known as the St. Augustine Public Burying Ground) in St. Augustine, Florida, located across from the historic City Gate was a Protestant burial ground between the years 1821 and 1884. The Spanish colonial city of St. Augustine, along with the entire Florida Territory became de facto American possessions after the 1819 signing of the Adams-Onis Treaty. The actual physical occupation of the city and Florida territory occurred in 1821. Prior to American occupation the Spanish city of St. Augustine was predominately Catholic and the only burial ground within the city, the Tolomato cemetery, was reserved for Catholics. Recognizing a need for a formal Protestant burial ground an area just outside the city gate was chosen by the new American administration in St. Augustine. The first burials occurred in 1821 just prior to a yellow fever epidemic which claimed the lives of a large numbers of the city's inhabitants. The cemetery until title to the cemetery property was acquired by the Rev. Thomas Alexander, who then turned over it to the Presbyterian Church in 1832, burials continued until 1884 when both Huguenot and Tolomato cemeteries were closed. The cemetery is believed to hold at least 436 burials according to city records. The cemetery although named "Huguenot Cemetery" isn't believed to contain any members of the Huguenots, a French Protestant sect started in the 16th century in France.

It is touted as being the oldest wooden school building in the United States. The exact date of construction is unknown, but it first appears on tax records in 1716. There are no extant wooden buildings in St. Augustine built prior to 1702 when the British burned the city. The oldest schoolhouse still standing in the United States is the Voorlezer's House built prior to 1696 and located in Historic Richmondtown in Staten Island, New York.The building is encircled by a large chain, placed there in 1937, to help anchor it to the ground in case of a hurricane. The walls are made of bald cypress and red cedar which are held together by wooden pins and iron spikes, however, recent maintenance has replaced the roofing, among other fixes. The schoolmaster and family lived on the second floor above the classroom and the kitchen was located in a separate building to reduce heat and threat of fire. The building originally belonged to Juan Genoply. The classroom was one of the first in the US to be co-ed, educating both boys and girls since 1788.
