The Millennium Stadium
This stadium is a landmark and puts the builders of Wembley to shame; the Cardiff one was finished on time and everything. Don't waste your money on a tour though having a peak into the changing rooms is about as exciting as it gets, and there won't be any hot sportsmen/women in there at tour time as it's all out of hours. Book tickets for an actual event: being part of a 72,500 audience is far more exhilarating. Itchy suggests embracing the Welsh game of rugby: watching 19 stone men run around with a ball is surprisingly fun. Or if you hate that kind of thing, they show a fair amount of footy matches too.
