The land that we now know as Ireland once lay below a vast sea that covered the earth. The ancient seabed filled with layers of dead sea creatures metamorphosed into

limestone. Over a process of millions of years, the land was uplifted forming hills and mountains. A series of ice ages further changed the landscape by sculpting out fjords and leaving valleys and lakes in their wake. The Burren in Western Ireland is a perfect place to explore these ancient processes.
