1. Melbourne Cricket Ground
The MCG is Melbourne's cathedral. Built in 1853, it holds 100,024 people and is the largest stadium in the Southern Hemisphere. If you want to understand why sport matters so much to this city, start here. It hosted the 1956 Olympics, two Cricket World Cup finals, and the AFL Grand Final every September. The first-ever Test cricket match was played on this ground in 1877. That kind of history doesn't exist anywhere else. Even without a match, the MCG tour (30 AUD) takes you through the players' rooms, out onto the ground, and into the Australian Sports Museum housed inside the stadium. The museum alone has enough cricket bats, footy guernseys, and Olympic memorabilia to keep sports fans busy for hours. On game days, forget the tour and buy a ticket instead. An AFL match at the 'G with 90,000 fans is one of the great sporting experiences on earth. The stadium sits in Yarra Park, a short walk east from Flinders Street Station or Birrarung Marr.
