The Oldest Wooden School House is a wooden structure located at 14 St. George Street in St. Augustine, Florida near the city gate. 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.

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.
