Monkwearmouth–Jarrow was a combination of two English monasteries run as a single community. Both were founded by Benedict Biscop. Monkwearmouth, built first, was a magnificent example of the Roman style of architecture. It housed one of the first stained glass works in England. Jarrow became the center of Anglo-Saxon learning in the north of England and contained the largest library in Anglo-Saxon England. Bede, the great Anglo-Saxon scholar, studied, taught and wrote there. The sister Anglo-Saxon monasteries were the UK nomination for World Heritage Site status in 2011.
