What these pictures are about.
A bit about the cliffs, provided by the Cliffs of Moher website:
"The Cliffs of Moher are one of Ireland's top Visitor attractions. The Cliffs are 214m high at the highest point and range for 8 kilometres over the Atlantic Ocean on the western seaboard of County Clare. O'Brien's Tower stands proudly on a headland of the majestic Cliffs. From the Cliffs one can see the Aran Islands, Galway Bay, as well as The Twelve Pins, the Maum Turk Mountains in Connemara and Loop Head to the South.
The Cliffs of Moher are home to one of the major colonies of cliff nesting seabirds in Ireland. The area was designated as a Refuge for Fauna in 1988 and as a Special Protection Area for Birds (SPA) under the EU Birds Directive in 1989. Included within the designated site are the cliffs, the cliff-top maritime grassland and heath, and a 200 metre zone of open water, directly in front of the cliffs to protect part of the birds' feeding area. The designation covers 200 hectares and highlights the area's importance for wildlife."
