8th century

The 8th century was perhaps best known in England for being the century of King Arthur. At some point in the century, the forces of King Arthur and Mordred met near Carbury and fought the Battle of Camlann. Merlin hid a dimension ship underneath nearby Lake Vortigern, linked to the battlefield via a cement tunnel. He marked the entrance with the message: "Dig hole here". The note was in the Doctor's handwriting. (TV: Battlefield)

From the late 8th to 11th centuries, the Vikings raided and traded with large areas of northern and central Europe. (PROSE: A History of Humankind)

The Book of Kells was written on the Scottish island of Iona in the 8th century. (AUDIO: The Book of Kells)

Still, it was a century only sporadically visited by the Doctor and their companions. The Second Doctor, Jamie and Zoe, for instance, travelled to Scandinavia at the beginning of the century. (PROSE: That Which Went Away) Also, the Seventh Doctor once stopped off in 8th century Britain for a game of conkers. (COMIC: Doctor Conkerer!)

Additionally, the Fourth Doctor and Sarah Jane went to Saxon England during a Viking raid circa this era. (COMIC: Woden's Warriors)
