La Unión — San Diego Fort ruins (El Salvador) (unverified)

The location as specified by the user — a 'San Diego Fort' ruin in the La Unión port area of El Salvador, reputedly haunted by sailor and soldier ghosts — is not documented in the supplied research materials. The provided sources instead reference other, unrelated entities named La Union/La Unión (a Philippine province and a Colombian city) and include unrelated news archives. No construction history, ownership records, archaeological descriptions, or witness reports for a San Diego Fort in La Unión, El Salvador are present in the provided sources. Similarly, there are no sourced accounts of apparitions, audio phenomena, material effects, or named spirits tied to this site in the supplied documents. Because the dataset contains no primary or secondary documentation for the Salvadoran site or its alleged hauntings, claims about the site's history, phenomena, or cultural significance remain uncorroborated and should be treated as disputed or unverified until better sources are provided.
