Estádio Milton Corrêa, usually known as Zerão, is a multi-purpose stadium located in Macapá, Brazil. It is used mostly for football matches and hosts the home matches of Amapá Clube, Esporte Clube Macapá, Oratório Recreativo Clube, Trem Desportivo Clube, Santos Futebol Clube (AP), São Paulo Futebol Clube (AP) and Ypiranga Clube. The stadium has a maximum capacity of 10,000 people and was built in 1990. The name (and the fame) come from the unusual circumstance that the midfield line supposedly lies exactly on the Equator - zero latitude -, thus causing each team to defend one hemisphere.
Zerão is owned by the Amapá State Government. The stadium is named after Milton de Souza Corrêa, who was a former president of the Amapá State Football Federation. The stadium is nicknamed after the neighborhood where it is located, Marco Zero (the neighborhood is named Marco Zero ("mark 0" in English) as it is located on the Equator). Zerão means Big Zero, denoting the zeroth latitude - Equator.
