Monks live in monasteries, which are mainly found in Europe, the U.K. and Asia. Monks are usually Christian, Buddhist and Hindu men.
The word monastery comes from the Greek term monos, which means alone. Monks withdraw from society and form communities devoted to religious practice. Monks usually spend a lot of time in prayer, and some orders or groups of monks are involved with the local population and provide medical or teaching services.
Monasteries are buildings where monks live and work, and most also include a chapel, church or temple. Their size ranges from one small building, housing a couple of monks, to large complexes occupied by tens or hundreds of monks. Some Buddhist monasteries are built in complex cave systems.
