The Estádio das Antas (officially Estádio do Futebol Clube do Porto) was the third (and longest occupied) stadium of the Portuguese football side FC Porto. It was in use from 1952 to 2004, replacing the earlier Campo da Constituição and later replaced by Estádio do Dragão. As well the stadium, it had an indoor arena and three training grounds. The club's offices were also split between the inside of the stadium and the Torre das Antas, built in front of the stadium during the 1990s.
