The Old City Jail in St. Augustine is described as a highly haunted location, with reported paranormal activity including the sounds of footsteps, barking dogs, wailing, and laughing. Visitors also report unpleasant smells, sudden cold spots, and experiences of being touched. The jail, in operation from 1891 to 1953, was a site of many violent criminals, several documented hangings, and unnatural deaths, which contribute to its reputation as one of the most haunted buildings in the country. Visitors and staff have heard inexplicable sounds like footsteps, barking dogs, wailing, moaning, and whistling, sometimes accompanied by laughter. Unpleasant aromas, such as sewage or sickly sweet smells, have been reported. Additionally, some feel the sensation of being touched on their shoulders or hair being tugged. Some spirits are believed to be residual energy, meaning they are present in the environment and repeat past actions without interacting with people. The jail was closed due to its poor conditions and the cruelty shown to inmates. It housed violent criminals and was the site of eight documented hangings and numerous other unnatural deaths during its time in operation. Some accounts mention the spirit of a jail keeper who died on the property, though this is not a primary source.
