Forte de São João Baptista de Ajudá

Forte de São João Baptista de Ajudá is a small European fortification in the town of Ouidah on the historically significant Slave Coast. Built in 1721 to participate in the transatlantic slave trade, it was the last of three European forts erected in that town for that purpose. After the early 19th-century legal abolition of the slave trade the fort lay abandoned for much of the period until it was permanently reoccupied in 1865. Modern references describe the structure as restored. The supplied research materials (Wikipedia, Wikidata, and an archival Portuguese historical/ethnographic work) provide historical, topographical, and restoration-related information but do not contain accounts of hauntings, named spirits, curses, apparitions, sounds, or other paranormal phenomena. Although the fort is sometimes—outside the provided sources—referred to in popular discussion as carrying curses linked to its role in the slave trade, such supernatural claims are not substantiated in the cited materials and therefore are not asserted here. Culturally and historically, the fort's significance derives from its direct connection to the transatlantic slave trade and Portuguese colonial presence in West Africa. The archival title in the bibliography indicates that older historical and ethnographic descriptions of the district and the kingdom of Dahomé exist for researchers, but those works were not excerpted here for additional claims about folklore or supernatural tradition.
