Presidio La Bahía is described as haunted by reports of soldiers' screams, constant footsteps when the site is closed, a feeling of being watched, and apparitions of soldiers, including Colonel Fannin, appearing in the courtyard. These phenomena are attributed to the Goliad Massacre, where many Texian soldiers were executed at the site in 1836, and some believe the site, including the chapel and mass grave, is a location for lingering spirits. Sightings of soldiers' ghosts and shadows. Hearing the screams of massacre victims and the sounds of footsteps when the museum is closed. A pervasive feeling of being watched. The ghost of Colonel Fannin is said to appear in the courtyard.
