Why were monasteries important during the middle ages?
give me three reasons !

They were centers of religion, and especially religious conversion when it came to the northern monasteries in Norse territory, and they were also centers of learning and scholarship - it tended to be that priests and monks were the ones that could read. Furthermore, monasteries were very, VERY rich places, full of decadent ornaments and all the trappings of the high religious life. In this way, they were sort of an extension of the Church's power and wealth.
