Hermitage (religious retreat)

A hermitage most authentically refers to a place where a hermit lives in seclusion from the world, or a building or settlement where a person or a group of people live religiously, in seclusion. Particularly, as a name or part of the name of properties its meaning is often imprecise, harking to a distant period of local history, components of the building material, or recalling any former sanctuary or holy place.
