In which country is the village whose shortened name is Llanfairpwll?

Lorraine , look at the photo

My granddad could pronounce that place, and he was English

I've been to Wales

passed it on my honeymoon in May 1985

Room Capo, you haven't put its full name with 58 letters, you have only written the name with 20 letters. Not a very good detailed explanation 😕
