The final three panels of the 230-foot long tapestry were recently completed in a community needlework effort based at a library on the island of Alderney.
The new panels completed the tapestry's tale of the Norman conquest of Britain. The story ends with the coronation of William the Conqueror as the country's new king in 1066.
"It is hard to describe really," said Pauline Black, the artist who designed the added scenes. "It is overwhelming how beautiful it is and I'm just astonished that we've finished."
The Daily Telegraph said the tapestry is made up of 50 scenes stitched in the 1070s, but the conclusion of the epic tale was missing. History buffs who want to know how it ends will have their chance when the new panels go on display at the Alderney museum later this year.
