While it technically hasn't hosted a WWE event, I would be remiss if I didn't mention the crown jewel of London, England in this countdown. Wembley Stadium opened its gates in 2007 and is considered to be one of the most spectacular sporting venues in the world, but it was its predecessor that held SummerSlam 1992. That version of Wembley Stadium was demolished in 2003 and replaced, but it still holds a special place in the hearts of many.

Big WWE events in England are few and far between and that is especially true of pay-per-views. There have been a handful of pay-per-views exclusive to the United Kingdom, but the only one to take place at Wembley Stadium was SummerSlam 1992 with a main event that featured "British Bulldog" Davey Boy Smith defeating his brother-in-law Bret Hart for the Intercontinental Championship in front of his countrymen.

Wembley was packed with 80,355 fans, which is the second-largest recorded attendance in WWE history behind WrestleMania III. WWE will never have another event in that specific arena, but New Wembley is certainly a possibility. There has been speculation about another SummerSlam being staged there or perhaps even a WrestleMania, so if and when the WWE decides to go back, Wembley may very well skyrocket up this list.
