Built by the Danes in the 17th century for Sweden, it changed hands under many rulers before the Danes were finally able to stake claim to the area and the castle. Before it was claimed by Denmark, it was used for trading precious metals, but once the Danes took power, it became a place to store slaves before shipping them. Later it became the headquarters of the Danish Gold Coast. Since then, it was used as a government building; when Ghana gained independence in 1957, it became the Presidential House. It remains the seat of government today, though there is controversy because of its ties to the slave trade. It is not open to walk-in visitors. Armed guards stand outside and they typically don't allow photos to be taken. Rules about pictures change sporadically, but it's best (safest) not to try.
Osu Castle is a castle located in Osu, a neighborhood of Accra, the capital city of Ghana, on the coast of the Gulf of Guinea.
