In the last decade of the 8th century AD, Norse raiders sacked a series of Christian monasteries located in what is now the United Kingdom, beginning in 793, with a raid on the coastal monastery of Lindisfarne on the east coast of England. The following year they sacked the nearby Monkwearmouth - Jarrow Abbey, and in 795 they attacked again, raiding Iona Abbey on Scotland 's west coast.
