The Roman Catholic hermitage of Our Lady of the Enclosed Garden is situated in the former Reformed church of Warfhuizen, a village in the extreme north of the Netherlands. It is the only Dutch hermitage currently inhabited by a hermit. The name draws upon the traditional epithet for the Virgin Mary of hortus conclusus or enclosed garden, a reference to the Song of Songs that indicates the Virgin's "perpetual virginity and at the same time her fruitful maternity".

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 lived 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. Secondary churches or establishments run from a monastery were often called "hermitages".
