Previous experience from only Connie Willis' To Say Nothing of the Dog had incompletely prepared me to visit Coventry Cathedral. (And inaccurately, for there were no time-travelling historians to be found. I looked.)
The destruction wreaked by the bombing and fires was accurate, though.
What remains is a memorial of and to World War II. The Cathedral was a real thing before it was a destroyed monument, and so it itself contained memorials like this one for World War I.
This post's theme word is intromit, "to enter, send, admit." Coventry Cathedral now intromits sunlight and the elements, as well as tourists and the religious.
