Ambry

An ambry (or almery, aumbry; from the medieval form almarium, cf. Lat. armarium, "a place for keeping tools"; cf. O. Fr. aumoire and mod. armoire) is a recessed cabinet in the wall of a Christian church for storing sacred vessels and vestments. They are sometimes near the piscina, but more often on the opposite side. The word also seems in medieval times to be used commonly for any closed cupboard and even bookcase.
