The famous San Fermín festival in Pamplona, Spain, is officially underway after the traditional "chupinazo" firework blast lit up the sky. Crowds of enthusiastic participants filled the city’s main square to kick off the week-long event, which includes the adrenaline-fueled bull runs and plenty of revelry.

Editor’s Note: This isn’t just any festival—San Fermín is a centuries-old tradition that draws global attention, blending danger, culture, and celebration. While it’s a thrilling spectacle for many, the event also sparks debates over animal welfare and safety. Either way, it’s a vivid example of how deeply rooted traditions continue to shape modern life.
