Its history is complex and deeply intertwined with the transatlantic slave trade.
In 1661 the Danes acquired the land for 3200 gold florins from the Ga Paramount Chief Okaikoi. They built a stone fort replacing an earlier Swedish structure. They named it Christiansborg after King Christian IV a Danish monarch. The castle’s early years focused on gold and ivory trade. However under Danish rule it quickly became a major hub in the horrifying slave trade.
The castle changed hands numerous times. The Portuguese briefly owned it adding a Roman Catholic chapel. The Akwamu people a powerful inland group even seized control for a year. Their leader Assameni cleverly infiltrated the Danish household working as a cook before seizing power. He later resold the castle to the Danes but kept the keys a symbol of Akwamu’s legacy.
The castle expanded significantly to accommodate the booming slave trade. The Danes shipped thousands of enslaved Africans from its shores. The dungeons at the castle ends held captives. They were moved through the infamous Door of No Return to waiting ships. The abolition of the slave trade in 1803 drastically affected the castle’s economy.
In 1850 Britain purchased the castle from Denmark. British colonial governors resided there until 1901. For a time it served as a constabulary mess and even a psychiatric asylum. In 1902 it once again became the seat of government. After Ghana’s independence in 1957 it became the presidential residence.
