Depending on whether you love myths and legends or if you are more grounded in science there are two ways to talk about the famous Giant's Causeway on the Antrim coast.
The beautiful animation at the top of this article tells the tale of the legendary warrior Fionn MacCumhaill, or Finn McCool in English, who built the amazing structure to cross the sea to fight the giant Benandonner in Scotland.
The other version actually brings you back further in time, millions of years in fact, telling how these unusual-shaped rocks formed to create an incredible natural design.
Around 60 millions years ago the world was going through some growing pains and beneath the surface there was a lot of volcanic activity.
With all this movement lava flowed up and cooled when it met the sea to form basalt rocks. Forty thousand make up what was to become known as the Giant's Causeway.
