Christianborg Castle is unique among the castles and forts along the coast of Ghana as it served as Government House during various periods in the 19th and 20th centuries and continues to play that role today. The building of the first lodge in the 17th century at Osu is attributed to the Swedish African company in 1657. The Swedish headquarters at Carolusburg Castle, Cape Coast was captured by the Danish Guinea company led by Heinddrick Caerlof who himself was formerly Swedish Africa Company’s Commanding Director. This resulted in all Swedish establishments including Osu lodge passing into the hands of the Danish Africa Company, Caerlof defected to the Dutch in 1659. The Danish Commander of Carolusburg was tricked into believing that Denmark had been conquered. He therefore sold Caroluburg to the Dutch and with it the former Swedish establishments including Osu lodge. The Ga Paramount Chief Okaikoi, disgusted with their trickery, asked the Dutch to leave Osu. In 1661, Jost Cramer, Danish government of Fredericksborg, near Cape Coast, acquired land from chief Okaikoi for 3,200 gold florins. The Danes built a stone fort to replace the earthen lodge and named it Christianborg (Christian’s fortress) after the former King of Denmark, Christian IV who had died in 1648.
