The Legend
According to Irish folklore, the giant Fionn McCool (Finn MacCumhaill) built a causeway across the sea to Scotland to confront the Scottish giant Benandonner, who had challenged him to a fight. On seeing the sheer size of his rival, Fionn had second thoughts - so his wife disguised him as a baby in a giant cradle. When Benandonner saw the size of the “baby,” he assumed Fionn himself must be enormous, and fled back to Scotland, tearing up the causeway behind him to stop Fionn from following - leaving only the Antrim end (the Giant’s Causeway) and, according to legend, a matching formation on the Scottish island of Staffa (Fingal’s Cave) as the causeway’s remains.
The Geology
The real explanation is no less remarkable: around 50-60 million years ago, volcanic activity sent molten lava flowing across the area; as it cooled and contracted, it cracked into the roughly hexagonal columns visible today, in a process called columnar jointing - seen at other basalt sites worldwide, including Iceland and Scotland’s Fingal’s Cave. Erosion has since exposed the columns, some reaching up to 12 metres, to form the landscape visitors see now.
Cultural Legacy
The legend has been retold for generations and remains a defining piece of Irish folklore, inspiring music, storytelling, and - most notably in visual art - the work of Susanna Drury, an Irish artist whose gouache paintings of the Giant’s Causeway (1739-40) won a Royal Dublin Society award and were later reproduced as widely circulated engravings, helping establish the site’s international reputation long before mass tourism.
Visiting
The Giant’s Causeway sits on the north Antrim coast a short drive from Bushmills, easily reached by car or public transport. The visitor centre offers exhibits on the site’s geology and folklore, guided tours, a café, and a gift shop. Nearby, the Carrick-a-Rede Rope Bridge - built by fishermen to reach a salmon-fishing island, spanning a 20-metre chasm - is one of the area’s other signature attractions, alongside coastal walks along the Causeway Coast Way.
