The St. Augustine Lighthouse is considered highly haunted, with reported paranormal activity including the spirits of children, a deceased lighthouse keeper, and mysterious phenomena like electrical activity, objects moving on their own, and the smell of cigar smoke. The main apparitions are the Pittee sisters, two young girls who drowned near the property, and Joseph Andreu, a keeper who fell from the tower. Visitors often report hearing the girls' giggling at the top of the tower and seeing children's footprints or even a little girl in Victorian clothing. Other presences include "The Man," a shadow figure in the basement, and the smell of cigars, linked to a former lighthouse keeper, William Russel. The Pittee Sisters: Two young girls who drowned when a supply cart flipped into the water during the lighthouse's construction are said to haunt the grounds. Visitors report hearing their giggling and sometimes seeing a little girl in a red dress or Victorian outfit, according to the St Augustine Light House museum website. Joseph Andreu: The spirit of Joseph Andreu, a former keeper who died after falling from the tower while painting, is sometimes seen looking out from the top of the lighthouse. A shadow figure known as "The Man" is often seen in the basement of the former lighthouse keeper's house. People report feeling feelings of foreboding and smelling cigar smoke when he is present. Mysterious electrical activity has been reported, particularly near the children's play table. The door at the top of the tower is often found open without triggering its alarm, and chairs have been moved or overturned. Child-like footprints have been found inside the keeper's house, even when no children were present. Coughing has been heard in the parlor of the keeper's house, which is attributed to William H. Horn, a former keeper who died from tuberculosis.
