Ourem, Portugal

If you're looking to move abroad, Ourem isn't exactly a tourist's dream. With just 13,212 residents, this small city in central Portugal is firmly focused on its role as a religious pilgrimage site, drawing up to 8 million visitors yearly to the Sanctuary of Our Lady of Fatima. While the town's medieval history and scenic limestone plateau are charming, locals grapple with a heavy bureaucratic burden - the plan to make Fatima an independent municipality was vetoed in 2003. And the climate, marked by wet, cold winters and hot, dry summers, can be a challenge. Overall, Ourem seems best suited for devout Catholics seeking a spiritual retreat, rather than a dynamic expat hub.
