Hear how it was carved from Cornish granite.

Made out of a single piece of granite, its surface has been carved with 1,800 nodes in the pattern of a Fibonacci spiral – the growth pattern found across the natural world in things like sunflowers, pine cones and ammonites. The same spiral is also visible in the roof of the Core building.

At more than 70-tonnes, Seed weighs as much as 10 elephants. The piece of stone it’s carved from is thought to be several hundred million years old.

How Seed was made and installed

One of the biggest sculptures in history made from a single piece of rock, Seed started life as a 167-tonne granite boulder extracted from De Lank Quarry, on the edge of Cornwall's Bodmin Moor, where Peter and his team spent more than two years painstakingly sculpting the rock.

Seed was lowered into the centre of the Core in 2007 using the largest crane in Europe.

Peter describes Seed as ‘an object of contemplation and meditation, a still, quiet hub; both fossil and seed’.
