The Seven Wonders of the United Kingdom

It's hard to believe that The Giant's Causeway on the North coast of County Antrim is not man (or giant) made. The causeway looks like a roadway into the sea. It is made of 40,000 interlocking basalt columns, some more than 12 meters high, produced by an ancient volcanic eruption. The tops of the columns form stepping stones, mostly hexagonal but also with four, five, seven and eight sides, leading from the foot of a cliff into the sea.

The Giant's Causeway was declared a World Heritage Site by UNESCO in 1986, and a National Nature Reserve in 1987. Today it is owned and managed by the National Trust.
