1) The Cliffs of Moher are 319 million years old!

They were formed through a combination of geological processes, including sedimentation and volcanic activity. All whilst dinosaurs roamed the Earth!

2) The layered rock that make up the Cliffs of Moher reflect environmental changes over million of years

The rock layers seen in the Cliffs of Moher are as result of the deposit of sediment in different environmental conditions over millions of years. This is why the cliffs appear to have different gradients of colour from their base up to the cliff edge.

The foot of the cliffs are made of the oldest rocks and get younger as they build towards the top. The lower layers are typically made up of shale, which is a fine-grained sedimentary rock formed from the compaction of mud and clay.

Above the shale layers, you can find sandstone layers, a coarser-grained rock formed from the consolidation of sand-sized grains.

3) The name “Moher” is Gaelic for “ruined fort”

The name “Moher” (pronounced “Mow-huh”) is believed to come from an old fort called “Mothar” or “Mhothair,” which once stood near the cliffs.

5) The iconic Cliffs of Moher Tower was built for visitors during the victorian tourist boom

O’Brien’s Tower was built in 1835 by a local landowner by the name of Sir Cornelius O’Brien. He built the observation tower purely to cater for the numerous tourists who were already visiting the cliffs during the Victorian tourist boom.

The tower has since become an iconic feature at the cliffs due to its spectacular viewpoint and reference marker for hiking trails.

8) The Cliffs are home to a diverse range of seabirds

The Cliffs of Moher are not only a breathtaking natural wonder but also serve as an important habitat for a diverse range of seabirds, including:

  1. Puffins – an adorable black seabird with distinctive orange, blue and yellow beaks.
  2. Razorbills – super cute black and white seabirds that nest in colonies on the cliffs that are easily recognisable thanks to their sharp, pointed bill.
  3. Kittiwakes – sea gull-like birds with white plumage and grey wings. They often nest on the cliffs in large colonies.

The Cliffs of Moher provide these birds with the perfect environment for nesting and breeding, whilst the colonies contribute to the ecological significance of the cliffs.

The birds also add to the wonderful biodiversity and beauty of the area too!
