The cliffs rise 120 meters (394 ft) above the Atlantic Ocean at Hag's Head, and reach their maximum height of 214 meters (702 ft) just north of O'Brien's Tower, eight kilometres away. The cliffs boast one of Ireland's most spectacular views. On a clear day the Aran Islands are visible in Galway Bay, as are the valleys and hills of Connemara.
O'Brien's Tower is a round stone tower at the approximate midpoint of the cliffs. It was built by Sir Cornellius O'Brien, a descendant of Ireland's High King Brian Boru, in 1835, as an observation tower for the hundreds of tourists that frequented the cliffs even at that date. From atop that watchtower, one can view the Aran Islands and Galway Bay, the Maum Turk Mountains and the Twelve Pins to the north in Connemara, and Loop Head to the south.
The cliffs consist mainly of beds of Namurian shale and sandstone, with the oldest rocks being found at the bottom of the cliffs. One can see 300 million year old river channels cutting through the base of the cliffs.

I'd just like to link to the original page with the picture of O'Briens Tower used in the article.
