Its SouthAfrica

The Hole in the Wall at Coffee Bay is a unique structure with a huge detached cliff that has a giant opening carved through its centre by the waves. The local Xhosa call this place "izi Khaleni", which means "place of thunder". During certain seasons and water conditions (high tide) the waves clap is such a fashion that the concussion can be heard throughout the valley.

The Legend of Hole in The Wall: Xhosa mythology tells a far more romantic tale of the sea people, semi deities who look like humans but have supple wrists and ankles and flipperlike hands and feet. A beautiful girl living on the Wild Coast, in a village near a lagoon, cut off from the sea by a mighty cliff, was seen by one of the sea people who became overwhelmed by her beauty and tried to woo her.

To cut a long story short: in dealing with the wrath of her father, the sea people enlisted the help of a huge fish who battered its way headfirst through the wall of rock. Through this hole spilled the sea people who swept the young Xhosa maiden away.
