The Quidditch World Cup Stadium
"Every time Muggles have got anywhere near here all year,
they've suddenly remembered urgent appointments and had
to dash away...bless them."
There is some inconsistency in dates with the World Cup. In GF8, Ludo Bagman welcomes everyone to the "four hundred and twenty second Quidditch World Cup". However, Quidditch through the Ages sets forth the history of the World Cup competition. It says that the Cup was first held in 1473, and held every 4 years since. That means that the Cup had been held around 130 times by 1994. Not even close to 422.
Also, if the Cup has been held every four years from 1473, then 1993 and 1997 would have been Cup-years, not 1994. However, the Quidditch World Cup of 1877 is known as The Tournament Nobody Remembers because, for reasons unknown, no one has any recollection of the matches taking place (thought they undoubtedly did). Therefore, the Tournament was restaged in 1878, and from then on the World Cup was held every four years from the new date (Pm).
