Osu Castle

Christiansborg Castle (Osu Castle), commonly known as Fort Christiansborg or just the Castle, is a 17th-century castle on the coast of the Atlantic Ocean’s Gulf of Guinea, near Ghana’s capital Accra. The first large fort was built by the Danes, and it has since passed through the hands of Denmark, Norway, Portugal, the Akwamu, Britain, and eventually post-independence Ghana. Christiansborg Castle is also remarkable among castles and forts in that it served as the seat of government in Ghana for the most of its existence, with a few exceptions, until the Jubilee House was built.The castle is the most visited among all the tourist sites in Greater Accra Region.
