As the United States' first and original haunted tour company with a long-standing reputation for quality research and world-class experiences, Ghost Tours of St. Augustine Inc. invites you to attend the only paranormal investigation in the ancient city to focus on its most haunted landmark! Explore the disturbing military history, macabre medical procedures, and the true Native American history and legends associated with the country's oldest stone masonry fort. This exterior-only tour of the longest extant building in the city also includes the frequently attacked defence outpost, the Santo Domingo Redoubt, as well as the famously haunted City Gates, and the terrifying Huguenot Cemetery.

This tour and investigation programme includes the use of shared equipment, such as EMF metres, spirit boxes, and more, which they supply and demonstrate how to use. You are also welcome to bring any of your own equipment. Photos and recordings of this guided programme are welcome and encouraged.
