My daughter was in London on 9-11-01 and she said there was a period of silence in downtown London when they got the word. Don’t remember how long she said it was but she said no one moved or spoke.
In Ireland they declared Friday of that week a whole day of mourning (see above). Nothing was open except for places that sold emergency supplies. We did not know if, or when, we could get out and I had brought only the right amount of medecine for our trip. I spent the afternoon in a Galway Pharmacy getting additional Lipitor. The pharmacist was so nice — called my home pharmacy in Wisconsin to work out the right measurement because US pills are in different dosages than the European counterparts. No charge for the long distance call.
The Cathedral was packed with tourists and townspeople. When we came out of Mass, the parking lot was filled with shoulder to shoulder people who could not get in and the priests distributed Communion to all who wanted it.
There were books of condolence that we could sign all over town and at the church too.
