Guanajuato City

A UNESCO World Heritage silver mining city built into a ravine, Guanajuato's pedestrianized callejones (alleys), the Beso del Callejón del Beso, and the underground road system replacing the old river bed create an urban experience unlike any other Mexican city, with 30% more narrow alleyways than #4 Puebla's historic core. The annual Festival Internacional Cervantino is the most important classical arts festival in Latin America, attracting over 400,000 attendees, double the attendance of its nearest rival.
