Located on the northeastern coast of County Antrim in Northern Ireland, this natural site comprises a dramatic stretch of coastline featuring distinctive hexagonal basalt columns. The geological formations result from ancient volcanic activity dating to the Tertiary period, when lava flows cooled and fractured into their characteristic polygonal shapes. The site is celebrated for its scientific significance as an exceptional example of columnar jointing in basalt, which has long attracted geologists and natural historians. The landscape combines the striking rock formations with rugged coastal scenery, creating both geological and aesthetic value. The interplay between the geometric precision of the columns and the raw power of the surrounding seascape characterizes the visual distinctiveness of this location. Its inscription recognizes the outstanding geological importance and the rare natural processes that have shaped this remarkable coastal phenomenon.
