#22: Castle of Good Hope — South Africa
Built by the Dutch East India Company between 1666 and 1679, the Castle of Good Hope is South Africa’s oldest surviving colonial building. Its pentagonal walls have witnessed centuries of Cape Town history. In its early days, it served as the colony’s center. It also was a prison and execution site. The most famous ghost said to haunt the castle is the Lady in Grey, a woman often seen weeping hysterically before she vanishes. Another infamous spot is the “Donker Gat,” or Dark Hole, a windowless dungeon where prisoners were held in nearly total darkness. Visitors report hearing voices and footsteps echoing from the castle’s many grim corners.
