DURDLE Door made out of mashed potato is just one of the wacky exhibits on display at the latest exhibition to pen in West Dorset.

Rocks: from axe heads to Zennor Head is designed to make you think twice about the ground beneath your feet.

Ancient flint tools and Victorian bottles of coloured sand sit next to contemporary art including the large image of Durdle Door made from mashed potato and peas, all brought together over many years by Portland artist Judith Frost.

Through this very personal collection, Judith tells the story of her fascination with the earth’s shifting and the ways we have used the rock and stone revealed.

Discover 17th century illustrations of rocks and minerals that contributed to the debate about the origin of fossils, the first images of Everest taken from the air in 1933, a fertility stone from India, a Pre-Raphaelite watercolour of igneous rocks and even stone sweets.

Alongside the exhibition is a programme of talks, walks and workshops.

It can be seen, Tuesdays to Saturdays, 10am to 4pm, until Saturday, June 6 at Bridport Arts Centre.
