The Mystery of Grim's Ditch

The Mystery of Grim’s Ditch

Grim’s Ditch is Buckinghamshire’s longest and largest heritage asset, but much of the history surrounding it still remains a mystery

Our Mystery of Grim’s Ditch project aims to uncover the secrets of this ancient earthwork, such as who created it and why? What it was it used for? Was it created as one continuous earthwork running through some of the southern counties? This project forms part of the heritage work that Chalk, Cherries and Chairs is undertaking across the Central Chilterns, uncovering information about the past and linking people to their local landscape.

About Grim's Ditch

Grim’s Ditch – also known as Grim’s Dyke – stretches through the Chilterns and across southern England. In places, it is a Scheduled Monument. The name encompasses a number of prehistoric bank and ditch linear earthworks of different dates, and which may have been built for different reasons.

Likely built during the Iron Age, the purpose of these earthworks remains a mystery, but they are generally considered to be too small for military of defensive use. They may have been used to mark boundaries or enclose land.

It is thought that Grim’s Ditch got its name from the the Anglo-Saxons who named things of mysterious origin ‘Grim’, a word derived from the Norse for devil and a nickname for Odin, the God of War and Magic.

About our project

In partnership with Buckinghamshire Council, our Mystery of Grim’s Ditch project looked to connect local people to the history of their landscape, as well as uncover some of the secrets surrounding it.

  • We engaged with the Chilterns Young Archaeologists Club (YAC) and Aylesbury YAC, offering visits and presentations, and facilitating artwork and creative writing around the subject.
  • We visited three schools in the Cental Chilterns area – Prestwood Primary, Great Kingshill and Thomas Harding – to provide talks and information on the Ditch in line with KS2 National Curriculum criteria on prehistory.
  • We offered guided walks and prepared a self-guided walk leaflet to show people the Ditch as it is today and link it back to the landscape and wildlife.
  • We undertook a Geophysical Survey of an area where there is a ‘gap’ in the Ditch to determine its nature. 34 young volunteers from the two Bucks YAC groups and our New Shoots group (all aged between 8 and 16) were accompanied by 8 adult volunteers to survey the gap using specialist equipment.

Chalk, Cherries and Chairs visit to Grim's Ditch

During winter, the CCC team took a fascinating walk with The National Lottery Heritage Fund around Grim’s Ditch to see the earthworks and learn more about the results of our project. Our colleague from Buckinghamshire Council who is running our Mystery of Grim’s Ditch project showed us part of the Ditch, some of the surrounding historic sites, and talked about the area’s history.
