Anchorite
In Christianity, an anchorite or anchoret (female: anchoress; from Ancient Greek ἀναχωρέω (anakhōréō) 'I withdraw, retire') is someone who, for religious reasons, withdraws from secular society to be able to lead an intensely prayer-oriented, ascetic, or Eucharist-focused life. Anchorites are frequently considered to be a type of hermit, but unlike hermits, they were required to take a vow of stability of place, opting for permanent enclosure in cells often attached to churches.
