List of monastic houses in Wales facts for kids

Kids Encyclopedia Facts

A monastic house is a place where monks or nuns live and pray together. This list tells you about the old abbeys, priories, and friaries, and other religious homes in Wales.

We've included smaller places like 'cells' (tiny monasteries) and 'monastic granges' (farms run by monks, especially if monks lived there). We also included places run by military orders like the Knights Templar and Knights Hospitaller. We haven't included hospitals unless they were also a type of abbey or priory at some point.

The locations are based on maps from the Ordnance Survey.
