Dun Briste is a 150-foot sea stack off County Mayo, Ireland, at Downpatrick Head. According to the legend, this impressive site broke off the mainland during a massive sea storm in 1393. Ships rescued those living on the cliffs who had fallen into the water.
During the 1980s, a team of scientists discovered remnants of a medieval house on the property. The discovery supports the theory that an arch leading to the rock once existed. After all, Dun Briste translates to “The Broken Fort” in Gaelic.
Now, we get to see what thousands of years of geological formation caused by rough wave erosion look like in one chunky layered tower of rock.
