Coenaculum
From Wikipedia, the free encyclopedia
Coenaculum, the term applied to the eating-room of a Roman house in which the supper (coena) or latest meal was taken. It was sometimes placed in an upper storey and reached by an external staircase.[1]
The Last Supper in the New Testament was taken in the coenaculum, the large upper room cited in St. Mark (xiv.15) and St. Luke (xxii.12).[1]
