Heydon is a village in Cambridgeshire situated on one of the highest places in the county with the nearby village of Great Chishill being the very highest. It is a village with lots of historical connections including the Anglo-Saxon earthwork called the Bran Ditch. The old Icknield Way path also passes through the village on its 110-mile journey from Ivinghoe Beacon in Buckinghamshire to Knettishall Heath in Suffolk.
Heydon Walk cache was hidden on 31 March 2002 by Mookey, then looked after for many years by EssexRambles, and is now in the CO-ship of GCZ Team, who adopted it on its 21st birthday on 31 March 2023. It is also now the second in our series of caches hidden close to the famous earthworks called the Cambridgeshire Dykes. This one is near a section of the Bran Ditch or Heydon Ditch (see map below).

Bran Ditch rises in Heydon and runs down the hill to Black Peak in Fowlmere and was probably constructed in the 6th century AD (early Anglo-Saxon). This map (After Malim et al 1996) is a map of South Cambridgeshire and shows the five Cambridgeshire dykes - Bran (or Heydon) Ditch, Brent (or Pampisford) Ditch, the northern Fleam Dyke (or High Ditch), Fleam (or Balsham Dyke) and Devil's Dyke, plus Roman roads.

A recent and very informative article on the Cambridgeshire Dykes and archaeological excavations associated with them is Malim, T. et al 1996 'New Evidence on the Cambridgeshire Dykes and Worsted Street Roman Road' in Proceedings of the Cambridge Antiquarian Society LXXXV, 27-122.
