The Animal flower Cave, near North Point, Barbados. It is the island's lone accessible sea cave. It was discovered by its seaward entrance in 1780 by two English explorers. The cave stands six feet above the high water mark although it was formed at sea level. This has occurred because Barbados is rising at 1 inch per 1000 years. The Cave has a coral floor which is estimated to be about 400,000 to 500,000 years old, whereas the younger coral section above the main floor is about 126,000 years old. This dating was carried out by the German Geological Institute.
