Monkwearmouth–Jarrow Abbey
In 794, just a year after the Vikings sacked Lindisfarne, the Vikings attacked Monkwearmouth and Jarrow. The flames were so hot the glass was melted. Both sites were abandoned for a time. Their location on the coast of Northumbria made them easy targets for Viking raids. The twin monasteries were rebuilt. Unlike many old ruins that disappear over time, the old walls of Monkwearmouth and Jarrow can still be seen. They are next to or part of the modern buildings that replaced the original buildings built in 674 and 682.
