The lonely chapel described here is the Chapel Perilous. Weston describes it in From Ritual to Romance as an isolated chapel often associated with a cemetery. A knight pursuing the Holy Grail comes upon the chapel at night or durng a storm and takes shelter there, only to be confronted by the violent spirit or demon living within it. Eliot ties his chapel to that of the Grail legend with images of graves, isolation, rain, and of course death.
