35 Cities That Feel Like a Different Country Without Leaving the U.S.

24. Helena, Montana – A Quiet Echo of Ireland

Helena may not be the first place that comes to mind when thinking of Irish-American heritage, but this scenic Montana capital is surprisingly steeped in Celtic culture. In the 19th century, Irish immigrants came to Helena during the gold rush, many of them working as miners and builders in the rugged Rocky Mountain terrain. Their legacy still shapes the city's identity today, from its historic architecture to its enduring traditions and Irish pride. As you walk the streets of Helena’s historic district, you’ll find churches and stone buildings built by Irish hands, including the Cathedral of St. Helena—a stunning Gothic structure inspired by the churches of Europe. Irish-themed pubs like the Blackfoot River Brewing Company and O’Toole’s serve local brews alongside hearty fare like shepherd’s pie and corned beef and cabbage. Throughout the year, Celtic culture is celebrated through music, storytelling, and community gatherings, but it’s St. Patrick’s Day when Helena truly shines.
