39. Estádio do Maracanã
Location: Rio de Janeiro, Brazil
Current teams: Venue for football matches between Botafogo, Flamengo, Fluminense, and Vasco da Gama. It hosted 2013 FIFA Confederations Cup, and it will host 2014 FIFA World Cup and 2016 Summer Olympics.
Apparently Brazilians are very, very, very, very fond of soccer, and for some reason they insist on calling it futebol! Kidding aside, Maracanã is simply one of the best venues in all of sports. A match of hometown rivals Fla v. Flu is about as legit a Brazilian experience as you can get without losing hair or needing antibiotics.
