-
A churchyard gate with a porch or shed forming a chapel either combined with it or contiguous to it, in which in England and on the continent it was formerly customary, and is still usual in some places, for a bier to stand during the reading of the introductory part of the service, before it is borne inside; a corpsegate. It is very commonly nothing more than a simple shed under which is the gate. Also spelled, archaically, lychgate.
