Osu Castle (Fort Christiansborg)

Osu Castle, also known as Fort Christiansborg, anchors Accra’s coastal history. Built by the Danes in the 17th century, it later served as a seat of colonial and post-independence government. Its stark white walls and oceanfront setting contrast with its difficult legacy tied to the trans-Atlantic slave trade. Guided visits (availability can vary) focus on layered political and social histories rather than ornate interiors. Come for context: the fort offers a sober, essential lens on Ghana’s past and the evolution of Accra, with nearby beaches and the Osu neighborhood adding convenience for a broader day’s exploration.
