All 4,147 Hill Forts in Britain and Ireland!

Dotted across the landscape of Britain and Ireland, hillforts have been part of our story for millennia and for the first time a new online atlas captures all of their locations and key details in one place.

A research team based at the universities of Oxford, Edinburgh and University College Cork has been helped by citizen scientists from across England, Wales, Northern Ireland, Scotland and Ireland.

Funded by the Arts and Humanities Research Council (AHRC), they have spent the last five-years sifting and recording information on all the hillforts across Britain and Ireland. They have discovered there are 4,147 hillforts in total, and have collated details for every one into one map.*
