A groundbreaking archaeological discovery at Fort Tantumquery is reshaping how Ghana’s colonial past is studied, as researchers turn to advanced technology to uncover long-lost military relics without disturbing heritage sites.
In a first for the country, a joint research team identified musket balls—rarely found in Ghana’s forts—offering fresh physical evidence of armed activity during European occupation. The discovery challenges the long-held focus on cannonballs as the primary artefacts of colonial warfare along Ghana’s coast.
The study, led by Kwame Nkrumah University of Science and Technology in collaboration with University of Ghana and the Ghana Museums and Monuments Board, relied heavily on cutting-edge geophysical tools rather than traditional excavation.
Using drone mapping, ground-penetrating radar and electrical resistivity imaging, the team detected buried features with over 80 percent accuracy while drastically reducing the need for invasive digging.
Lead researcher Cyril Dziedzorm Boateng described the approach as a turning point for archaeology in Ghana, demonstrating that modern science can reveal hidden history while preserving fragile sites.
Beyond the musket balls, the team uncovered pottery, smoking pipe fragments, metal objects and structural remains—clear indicators of European presence at the fort, which dates back to the 1720s but had never been formally excavated.
The findings suggest that Fort Tantumquery played a more active military role than previously documented, offering new narratives about colonial encounters on the Gold Coast.
Experts say the implications go beyond historical curiosity. The integration of geophysics into archaeology could transform heritage preservation, support tourism development and create new opportunities for scientists and researchers.
Professor Samuel Asare-Nkansah noted that such discoveries could help prioritise conservation efforts while providing compelling, evidence-based stories to boost Ghana’s cultural tourism sector.
With support from international partners including UNESCO-linked funding, the project is being hailed as a model for future exploration of Ghana’s forts and castles—many of which remain unexplored and at risk of being lost over time.
