In recent days there have been reports of serious damage to a section of Offa's Dyke, which have involved the levelling of the embankment and the filling of the ditch, on a site towards its northern end.
Two of these reports are here, from the BBC Reports of damage to Offa's Dyke near Chirk are investigated , and from the Daily Mail at Offa's Dyke: 'Travellers' flatten 50 yards of 8th century monument
Due to its nature the Dyke is liable to damage and erosion, and its care and preservation should be a priority with local communities as well as those formally charged with its care like CADW.
In my view the damaged section in this instance should be reinstated, and those responsible should be pursued with the full rigour of the law. Unfortunately that does not happen in far too many cases of this sort, and vandalism is accepted or tolerated by authorities who should mete out real punishments for such offences. Ignorance is no excuse, and should not be accepted as one. Who in that area has not heard of Offa's Dyke? A spell in prison might give time for the offenders to read some books on Anglio-Saxon history - and if they can't read, time to learn how.
