Many claim that Guanajuato, a World Heritage Site, is the most European feeling city outside of Europe. Anywhere! The former mining town's opulent mansions, cobblestone streets, and perfectly preserved colonial center mimic a quaint Spanish town from the 17th century. And like Europe, those streets are narrow (so much so that cars can’t pass through most of them), winding, and walkable. Several of the town's churches have even been designated by UNESCO as some of the best examples of Baroque architecture in the Americas.
