Scheduled Monument Report:
This Dyke system looks like it was constructed over a period of years if not centuries. It connects on both ends the Paleochannels and it has an unidentified Dyke withing part of its alignment to the SE which seems to turn south then east until it connects to the same Paleochannel as Grim’s Dyke. To the West of the exit of this Dyke into the Paleochannel is the Site of Peterborough Castle – which would seem to be the logical place to take the quarried materials for either processing or trading.
What is quite remarkable about this area around the Scheduled monument is the excessive number of Quarry pits. Some of these quarry pits are on roads – suggesting the continuation of quarrying in recent (Roman?) periods – but over 50% are not connected by any road but lay on the shorelines of the prehistoric waters – which suggests that they are at least Mesolithic/Neolithic in date.

Robert John Langdon has also created a YouTube web channel with over 100 investigations and video documentaries to support his classic trilogy (Prehistoric Britain). He has also released a collection of strange coincidences that he calls ‘13 Things that Don’t Make Sense in History’ and his recent discovery of a lost Stone Avenue at Avebury in Wiltshire called ‘Silbury Avenue – the Lost Stone Avenue’.

Langdon has also produced a series of ‘shorts’, which are extracts from his main body of books:
