Cliffs of moher ireland

The Cliffs of Moher, on Ireland's west coast, are one of the country's most iconic geological formations, reaching heights of up to 214 meters.

About this subject

The Cliffs of Moher are located in County Clare, in the Burren region, stretching approximately 14 kilometers along the Atlantic Ocean. Formed during the Carboniferous period, about 300 million years ago, layers of shale and sandstone were shaped by coastal erosion over millennia. The highest point, called Knockardakin, reaches 214 meters. The O'Brien Tower, a stone structure built in 1835 by Sir Cornelius O'Brien, serves as a historic viewpoint offering panoramic vistas. The site is one of Ireland's most visited tourist attractions, receiving over 1.5 million visitors annually, and was featured in films like "The Princess Bride" (1987) and "Harry Potter and the Half-Blood Prince" (2009). The area hosts important seabird colonies, including puffins and northern gannets, and is designated as a Special Protection Area by the European Union. The geology also reveals marine fossils, evidence of an ancient seabed.
