Major defensive dyke discovered

The Taylor Wimpey excavations at Hyderabad Barracks produced their first surprise today – a section of what is apparently a very large ditch about 8 m across. It seems as if  the ditch could be part of the Berechurch Dyke which, until now, was not thought to have extended this far north. A lot more work has to done though so that we can recover dating evidence and section the ditch to make sure it is what it appears to be.
