n.

early 13c., from Old French chapele (12c., Modern French chapelle), from Medieval Latin cappella “chapel, sanctuary for relics,” literally “little cape,” diminutive of Late Latin cappa “cape” (see cap (n.)); by tradition, originally in reference to the sanctuary in France in which the miraculous cape of St. Martin of Tours, patron saint of France, was preserved; meaning extended in most European languages to “any sanctuary.” (While serving Rome as a soldier deployed in Gaul, Martin cut his military coat in half to share it with a ragged beggar. That night, Martin dreamed Christ wearing the half-cloak; the half Martin kept was the relic.)

a holy place or sanctuary, occurs only in Amos 7:13, where one of the idol priests calls Bethel “the king’s chapel.”
