Christmas Markets/Margaí na Nollag in Ireland
It looks like a Christkindlsmarkt but it is actually the Christmas market in Galway/Gaillimh, apparently one of the oldest and largest in Ireland. And Poblacht na hÉireann seems to have any number of other neat Christmas markets around the country.
I doubt if people really say Margaí na Nollag, but I'm sure they would if they had completed the Duolingo Irish tree. :D
There's also a big Christmas market in Belfast/Béal Feirste.
And not to be outdone, Chicago (the city that dyes the river green for St. Patrick's Day/Lá fhéile Pádraig) has just recently started an Irish Christmas Market of its own. No idea how Irish these folks may be, but they're really cute.
Galway! My City! (okay im from the countryside beside Galway :P )
Cork/Corcaigh started an annual Christmas market a few years ago, but it's got a long way to go before it'll compete with Galway's lovely market.
My seven year old has had his annual go-around on the carousel, though, and once he's had his spin on the ferris wheel, too, we can call it good for another year:
