The Peterbrough Chronicle. The Anglo-Saxon Chronicles refer to a collection of old writings and manuscripts kept by monasteries across England. They are written in blackletter and tell the history of the Anglo-Saxons. The recording started in the 9th century during the reign of Alfred the Great and stopped at different times in different regions. The Peterborough chronicle was still being updated as late as 1154.
The Bayeux Tapestry - chronicles the events leading up to the Norman conquest of England. It is actually and embroidered cloth and is nearly 230 feet long. The fact that it survived in such amazing shape since it's creation (no one knows exactly when but it is mentioned in the 1400's) is incredible... Been there!
