St Patricks' Day is also quite big in Malta. I was totally unaware of this when I was there in 2017. I was in Spinola, St. Julians' Bay, and I'd spotted a few notices about road closures and diversions for Sunday afternoon. I didn't expect what happened, as the whole island of Malta seemed to descend on Spinola Bay, with all their Irish themed clothes and headwear. See here.

But I used to go to St. Patricks' school in Collyhurst, Manchester and every year on St. Patricks' Day, we were given shamrock to wear. I didn't need to do this as I had my own, sent from Ireland to my grandparents, who gave us all a small piece. Oh yes! Low lie the Fields of Athenry! Moiya!
