Legend states that the ancient city of Kilstiffen lies hidden underwater at the base of the spectacular cliffs of Moher. It is said that years ago the city’s Chieftain lost the golden key of the castle. As a result, the city would remain underwater until the key could be found. Some locals claim that on calm days parts of Kilstiffen can be seen below the surface, while others state that every seven years the city rises above the waters. But beware, legend also states that anyone who catches a glimpse of the hidden city will die. As for finding a golden key when you visit, who knows what could happen!
