The Castle of Good Hope has a secret tunnel - Apparently.
The Castle of Good Hope, a 17th-century Dutch fortress in Cape Town, South Africa, has a hidden tunnel system that was only discovered in 1973. The tunnel, which stretches over 400 meters, was built in the 17th century to allow the governor of the castle to escape in case of an attack. Today, parts of the tunnel are open to the public as part of a museum tour. Archaeologists have confirmed the tunnel's existence through excavations and historical records.
