The majestic Cliffs of Moher are one of Ireland’s most spectacular and most visited tourist attractions and tower 213m (700 ft) above the Atlantic Ocean. The best vantage point from which to see the Cliffs is O’Briens Tower, constructed in 1835 by Cornelius O' Brien, a local Member of Parliament who was responsible for many other local landmarks, and restored in 1970. The locals know each of the cliffs by name from north to south: Aillenasharragh, Carrickatreel, Knockardachuan, Branawnmore, Stookeen and Hag's Head. Visitors also go to the cliffs to see the rich birdlife of the area, including puffins, shags, kittiwakes and razorbills. Nearby is an area known as the Burren consisting of rolling hills and cliff faces covered in limestone rock. The area supports a diverse range of flora and fauna and is also famous for its megalithic tombs and monuments that pre-date the Egyptian pyramids.
