Based on 4,216 reviewsPrincipality Stadium stands on the east bank of the River Taff. Its spaceship-like exterior is truly impressive. Built for the 1999 Rugby World Cup, this three-tier stadium features 72,500 seats and a retractable roof. During major events, the entire city comes alive. Beyond sports, many superstars have graced its stage, with artists like Rihanna and Bruce Springsteen holding concerts here. Take a stadium tour to explore the interior up close, step into the player locker rooms, walk through the player tunnel, or visit the VIP boxes—it's an experience you won't want to miss.
