A place where lamas, who are Buddhist monks, live and practice their religion.
The travelers visited a lamasery nestled in the mountains, where they learned about Buddhist traditions.
Lamasery is formed from 'lama' (from Tibetan 'lama', meaning a spiritual teacher or guru) and '-sery' (from Latin 'seria', meaning a place or collection). The word refers to a place where lamas, or spiritual teachers, reside and teach.
Think of a 'lama' as a spiritual teacher and '-sery' as a place, so a lamasery is a place where spiritual teachers gather.
