Monastic communities in this period often held overlordship over a large non-monastic population in order to provide, via feudal dues/taxation, the necessary goods to sustain the monastic community. So there would be a lot of traffic of non-monastics coming-and-going, especially in larger or more prosperous monastic estates.
