"The Dutch East India Company built this pentagonal fortress in the late 17th century to protect its burgeoning Cape Colony, and the British later used part of it as a prison with a torture chamber. Several ghosts reportedly wander the grounds, including that of a tall man walking along and falling from the ramparts, and that of Lady Anne Barnard, who once entertained important visitors to the fort. Another curiosity: The bell in the bell tower sometimes rings all by itself, despite being blocked off by bricks hundreds of years ago. Visitors can tour the fort and learn more about South African history in the Cape Heritage Museum." - Travel + Leisure Editors
