The Quidditch World Cup Stadium was a colossal, temporary structure erected by the British Ministry of Magic to host the 422nd Quidditch World Cup Final between Ireland and Bulgaria. According to Arthur Weasley, a team of several hundred Ministry of Magic employees worked for an entire year to construct it. From the outside, the stadium's walls were a shimmering gold, reaching a height equivalent to a cathedral. It was built in a vast oval shape, described by Harry Potter upon first sight as looking like a gigantic golden bowl. To prevent detection by Muggles, the entire area, including the stadium and the surrounding campsite, was protected by powerful Muggle-Repelling Charms. The local Muggle groundskeeper, Mr. Roberts, was subjected to numerous Memory Charms to prevent him from noticing the influx of wizards and the sudden appearance of the massive structure. Inside, the stadium was a vast cavern of gold. The pitch was a perfect oval of velvety green grass with three fifty-foot-high golden goal hoops at each end. Ten tiers of seats, accommodating one hundred thousand spectators, rose steeply around the pitch. On either side of the stadium were enormous blackboards that magically displayed the score, advertisements for products like Bertie Bott's Every-Flavour Beans, and replays of key moments during the game.
The stadium is a central location in the early chapters of Harry Potter and the Goblet of Fire. It serves as the venue for the much-anticipated final match of the Quidditch World Cup. Harry Potter, Hermione Granger, and the Weasley family attended the match, sitting in the prestigious Top Box as guests of the Ministry of Magic. Within the stadium, Harry witnesses the grand spectacle of an international wizarding world event, including the pre-match entertainment provided by the national mascots: the Veela for Bulgaria and Leprechauns for Ireland. The match itself is a significant event, showcasing the incredible flying prowess of Viktor Krum, whom Harry admires despite him playing for the opposing team. The vibrant and celebratory atmosphere inside the stadium provides a stark contrast to the terror of the Death Eater attack that occurs at the campsite later that night, marking a turning point from a joyful sporting event to the ominous return of Lord Voldemort's followers.
