Built rather quickly after a fire, Chartres Cathedral was constructed according to the precepts of Sacred Geometry—or so one learns while researching the internet—the matter not being generally known. Being in it is like walking through a nautilus shell: one hears sound rather differently. Of course, that may be my imagination, but so it seemed in the time that I was there with Mr. Husband. It's truly one of the most inspiring places I have ever been in, and when in Paris again, we will makes the trip to see it again. The windows alone are extraordinary. Alas, we did not hear the organ, which is nestled high upon the transept. A guided tour, which is given at noon (don't be late), is worth taking, being given by an Englishman who has doing just that for the last 30 years or so. Really. It's an incredible place which you must experience yourself.
