About Us

Welcome to Osu Castle, a monumental symbol of Ghana’s layered past and evolving future. Known historically as Christiansborg Castle, this striking structure perched along the coast of Accra stands as a physical chronicle of centuries of trade, colonization, political power, and now—heritage preservation. Once the seat of governments, both colonial and post-independence, Osu Castle is now open to the public as a museum, offering an immersive experience into the heart of Ghana’s political and cultural history.

Our History: From European Fort to Presidential Seat

The origins of Osu Castle date back to the mid-17th century. The land on which the castle stands was first utilized by the Portuguese in the 1550s. Later, in 1659, the Danes—through the efforts of a merchant named Heinrich Carloff—established a fortified trading post here. It was officially named Christiansborg, meaning "Christian’s fortress," in honor of the Danish King Christian IV.

Over the centuries, the castle changed hands numerous times. It was captured by the local Akwamu people in 1693, who held it briefly before selling it back to the Danes. The Akwamu left with the symbolic keys to the castle—keys that are still held today as a cultural artifact by the Akwamu traditional authorities.

In 1850, the Danish sold Christiansborg and their other possessions on the Gold Coast to the British. The British transformed the castle into the administrative seat of the colonial government. When Ghana achieved independence in 1957, the castle retained its significance, becoming the official residence and office of the President of Ghana.

The castle continued to serve as Ghana’s executive seat for decades, housing notable heads of state and serving as the venue for key political decisions and historical events. In 2013, the presidency officially moved to Jubilee House, and Osu Castle was eventually repurposed as a museum under the stewardship of the Ghana Museums and Monuments Board.

Today: A National Museum of Leadership and Governance

Osu Castle has now been transformed into a public museum known as the Presidential Museum of Leadership and Governance. It is dedicated to preserving and presenting the historical and political legacy of Ghana, with a particular focus on the country’s journey from colonial rule to independence and democratic governance.

As a museum, the castle offers guided tours through its preserved chambers, dungeons, halls, and gardens. Visitors can walk the same corridors once used by colonial governors and Ghanaian presidents alike. The museum features exhibits of archival photographs, official documents, furniture used by heads of state, and personal effects of key Ghanaian leaders.

One of the most powerful parts of the castle is the former slave dungeon and the infamous “Door of No Return,” through which many Africans were once forced onto ships bound for the Americas. This section of the museum provides an important, reflective space to confront the brutal history of the transatlantic slave trade.

Visiting Osu Castle

Osu Castle is now open to the public and welcomes both local and international visitors. Guided tours are available and recommended for a deeper understanding of the site’s rich and complex history.
