specific cities/towns in italy (and other european countries!) for celiac heaven?

my partner and i have decided to spend some time in europe! we’ll have three months to travel around and my main priority is finding cities that are good for celiac. we live in a country where celiac is very hard and i’ve been constantly disabled. i’ve read all the subs here about italy and spain but would like to know if anyone has any specific suggestions. i assume big cities are better but are there some smaller cities/big towns out there are that are good too?

edit: will also be spending time in ireland and UK if you have suggestions for those!
