Easily the most recognisable of Ireland's tourist attractions, the Cliffs of Moher in Co. Clare are visited by huge numbers of people each year. Standing over 200 metres at their highest point, they are about a third the height of the highest sea cliffs in Ireland. That honour goes to the cliffs at Croaghmore on Achill Island. Nevertheless, the sheer vertical drama of the Cliffs of Moher is undeniable.
You can see O'Brien's Tower in this photograph. It was built in 1835, probably as an observation tower for Victorian tourists.
The massive stack of Branaunmore is 67 metres high and must have once been connected to the cliffs by an arch.
