About Arena das Dunas
In Natal, Brazil, the football stadium Arena das Dunas, also called the Dunes Arena, has room for 31,375 spectators. Christopher Lee, a sports architect at Populous, designed it. It hosted football matches during the 2014 FIFA World Cup in Brazil, when its seating rose to 42,000. Its site replaced the Machadão, which was torn down in 2011.
The new project replaced an earlier scheme called Estádio Estrela dos Reis Magos, which would have stood in the neighboring municipality of Parnamirim. The stadium lies beside Senador Salgado Filho Avenue, which is the BR-101 highway, and the Complexo Viário do Quarto Centenário already serves that multi-lane road. FIFA inspectors gave the project high praise.
