Brimham Rocks

Brimham Rocks is an amazing natural landscape, formed over millions of years. The dramatic rocky outcrops left by this process have shaped the use and history of this place and fascinated people for more than 250 years.

The Rocks are made of Millstone Grit, created in a river delta 380 to 320 million years ago. This layer lifted up as the Pennines formed some 22 million years ago. Weathering then split the rocks along vertical joints and horizontal weaknesses. The last Ice Age, 10 to 18 thousand years ago, wore away softer rock and left the dramatic shapes you can see today. Erosion by wind, rain, frost, sun and people continues to this day.

For over 200 years, Brimham Rocks has inspired writers and artists, nurtured wildlife, enthused naturalists, and excited visitors. We hope you too will enjoy and be refreshed by this wonderful place.
