Offa's Dyke

Offa's Dyke near Clun

King Offa was King of Mercia from AD797 to AD796.

He was attacked by British people living in what we now call Wales.

He organised the building of a large earthwork. It marked a boundary so it was clear when the Britons had invaded his Kingdom.

Named Offa's Dyke, it was an eight metre high mound of earth which ran in a rough line north to south for 80 miles.

We cannot be sure how useful the dyke proved to be, but it certainly showed how organised and powerful King Offa was.
